Best Rigol Digital Storage Oscilloscopes for Hobbyists

The Short Answer: Which Rigol DSO a Hobbyist Should Actually Buy

The best Rigol digital storage oscilloscope for most hobbyists in 2026 is the Rigol DHO814 — 100 MHz of bandwidth, four analog channels, a 12-bit ADC, up to 1.25 GSa/s sampling and a genuinely responsive 7-inch touchscreen, typically selling somewhere in the $600–$750 range. It is the point where “cheap scope” stops meaning “compromised scope.” If your budget tops out lower, the Rigol DHO804 gives you the identical platform with 70 MHz of bandwidth for roughly $400–$500, and buying four channels at that price beats buying two channels with more bandwidth almost every time for hobby work. If you mostly repair audio gear, chase power-supply ripple and decode slow serial buses, the two-channel Rigol DHO802 at about $300–$350 is the cheapest genuinely modern entry point into the Rigol line. And if you need to watch digital logic alongside analog signals, the Rigol MSO5074 adds 16 logic channels and a much faster 8 GSa/s front end for around $1,100–$1,500.

Everything below explains why those four land where they do, what the numbers on a Rigol datasheet actually buy you for a breadboard, an Arduino, an ESP32, a Class-D amplifier or a switch-mode power supply, and where the money is wasted. There is a full section for every current Rigol model a hobbyist might realistically consider.

Quick picks by situation

• Best overall for hobby electronics: Rigol DHO814 — 100 MHz, 4 channels, 12-bit, touchscreen.
• Best under $500: Rigol DHO804 — 70 MHz, 4 channels, same 12-bit platform.
• Cheapest modern Rigol: Rigol DHO802 — 70 MHz, 2 channels.
• Best for audio and precision small-signal work: any DHO-series 12-bit model; the DHO814 is the value pick.
• Best for mixed-signal / microcontroller bus debugging: Rigol MSO5074 or MSO5104 with 16 digital channels.
• Best for RF-adjacent and fast-edge work on a budget: Rigol DS1202Z-E — 200 MHz, 2 channels.
• Best used-market bargain: Rigol DS1054Z if you find one in good condition, but understand it is 8-bit and non-touch.
• Best step-up for serious bench work: Rigol DHO1074 or DHO1204 with 2 GSa/s and 100 Mpts of memory.

How to Choose: The Six Numbers That Actually Matter

Rigol’s catalog looks confusing because the model numbers encode bandwidth in a way that is not obvious (the “1054” in DS1054Z means 50 MHz, 4 channels; the “814” in DHO814 means 100 MHz, 4 channels). Once you strip the naming down, every purchase decision reduces to six specifications. Two of them are hard limits you cannot work around. Four of them are quality-of-life.

1. Bandwidth — the only spec that cannot be fixed later

Bandwidth determines the fastest edge your scope can show without lying to you. The relationship is not a suggestion, it is arithmetic: a signal’s rise time and the bandwidth needed to reproduce it are linked by the approximation BW ≈ 0.35 / rise time. A 10 ns edge needs about 35 MHz. A 5 ns edge needs about 70 MHz. A 2 ns edge needs about 175 MHz.

Critically, an under-bandwidth scope does not simply “miss” fast edges — it makes them look slower and rounder than they are, which can hide ringing, overshoot and ground-bounce problems that are the entire reason you bought the scope. If you are debugging a signal that is supposed to have clean edges and your scope shows a smooth curve, you may be looking at the scope, not the circuit.

A second trap: the bandwidth figure is specified at the input connector, and a standard passive 10:1 probe costs you bandwidth. A “100 MHz” probe on a 100 MHz scope does not give you a 100 MHz system. A reasonable rule is to assume the probe-plus-scope combination delivers roughly 70–80% of the lower of the two ratings, so a 100 MHz scope with the bundled probes behaves more like a 75–85 MHz instrument in practice. That is one reason buying one bandwidth tier above what you think you need is rarely a waste.

2. Sample rate — and the interleaving trick you should know about

Nyquist says you need more than twice the highest frequency of interest. Practical scope design says you need far more than that, because a digital storage oscilloscope reconstructs the shape of a waveform, not just its fundamental. The industry convention is 4x to 5x the bandwidth in real-time sample rate. A 100 MHz scope therefore wants at least 400–500 MSa/s, and Rigol’s DHO800/900 series delivers up to 1.25 GSa/s, comfortably above that.

Here is the part most buying guides skip: on nearly every budget scope, the headline sample rate is only achieved when one or two channels are active. The ADC is shared. Turn on all four channels and the per-channel rate typically drops to half. A scope advertised at 1.25 GSa/s may run each of four channels at roughly 625 MSa/s. That is still fine for a 100 MHz instrument, but it matters if you bought a scope specifically for its sample rate and then plan to use all four channels simultaneously — which, if you bought a four-channel scope, you probably will.

Some scopes also offer equivalent-time sampling (ETS), which can push the effective sample rate far higher for strictly repetitive signals. ETS is useful for characterizing a stable clock and useless for catching a glitch that happens once.

3. Channel count — why four beats two more often than you think

Two channels is the classic hobbyist configuration and it is genuinely enough for a lot of work: input versus output of an amplifier, clock versus data, supply rail versus ground reference. But four channels changes what kinds of questions you can ask.

With four channels you can watch an SPI bus directly — clock, MOSI, MISO and chip select simultaneously — and decode it in software. With two you are guessing. With four you can look at a three-phase motor driver, or a half-bridge with high-side gate, low-side gate and switch node. With four you can trigger on one event and simultaneously capture the cause and the effect on separate rails. With four you can also use two channels for a differential measurement and still have two left over.

The counter-argument is real: four-channel scopes cost more, take up more bench space, and the per-channel sample rate is lower when all are active. But the price gap between a two-channel and four-channel model in the same Rigol family is usually $100–$150, which is small compared to the cost of buying a second scope later. For a first serious scope, four channels is the better default.

Digital channels are a separate category. A mixed-signal oscilloscope (MSO) adds 8 or 16 logic inputs that show up as timing-diagram traces alongside the analog ones. If you spend your time on microcontroller buses, an MSO saves you from squinting at analog traces trying to decide whether a line is high or low.

4. Memory depth — the spec that determines whether you catch the glitch

Memory depth is how many samples the scope stores per acquisition. It is the most underrated specification on the datasheet, because it directly determines how long a window you can capture at full sample rate.

Capture time is simple arithmetic: capture time = memory depth ÷ sample rate. At 1.25 GSa/s, a 25 Mpts record gives you 20 milliseconds of full-rate capture. That sounds generous until you realize a slow serial burst at 9600 baud with a 50 ms gap will not fit, and you will be forced to drop the sample rate to see the whole event — which means you lose the fast edges inside it.

This is why deep memory matters more than people expect. A scope with 100 Mpts at 2 GSa/s gives 50 ms of full-rate capture, which comfortably swallows a full I²C transaction, a UART frame with gaps, or a power-up sequence. Rigol’s DHO1000 series and MSO5000 series are the deep-memory options; the DHO800 series at 25 Mpts is the entry level, and it is enough for most hobby work but not for everything.

One caveat: deep memory slows the scope down. At maximum depth, the update rate (how many waveforms per second the screen refreshes) drops, and the instrument feels sluggish. Good scopes let you switch to a shallower memory mode for interactive probing and a deep mode for one-shot captures. Rigol’s DHO and MSO series both expose this, and it is worth learning where the setting lives.

5. Display and interface usability

This is the specification that determines whether you enjoy using the instrument or dread it. Three things matter.

Resolution and size. A 7-inch 1024×600 panel is the current budget baseline and is usable, but four traces plus measurements plus a menu on that screen gets crowded fast. A 10.1-inch 1280×800 panel — found on the DHO900 and DHO1000 series — is a meaningful upgrade in daily comfort, not a luxury.

Touch. Rigol’s DHO series uses a capacitive touchscreen with pinch and drag for zooming and panning. Being able to drag a waveform and zoom into an edge with two fingers, rather than pressing a menu button eleven times, is the single biggest usability change in budget scopes over the past several years. The older DS1000Z series is menu-and-encoder only, and it feels its age.

Physical controls. Every DHO-series scope still has a real vertical gain knob per channel, a horizontal timebase knob and a trigger level knob. Do not underestimate this. A touchscreen-only interface is worse for probing, because your hands are already busy holding a probe. The ideal layout is a large touchscreen plus dedicated rotary knobs, which is what Rigol ships.

6. Software features — what separates a usable scope from a frustrating one

Firmware is where budget scopes live or die. The features worth checking before you buy:

• Serial decode. I²C, SPI, UART, and sometimes CAN and LIN. On many Rigol models this is a licensed option rather than standard, so confirm what is included and what is an add-on.
• Segmented memory. Captures a burst of events with minimal dead time between them, then lets you step through them one at a time. Invaluable for finding an intermittent glitch in a repeating signal.
• FFT. Turns the scope into a crude spectrum analyzer. Budget FFT is not a substitute for a real spectrum analyzer, but for finding a switching frequency, spotting a harmonic or confirming a filter roll-off, it is genuinely useful. Deeper memory improves FFT resolution substantially, which is another argument for the deep-memory models.
• Bode plot. Found on the DHO900S and some other models with a built-in waveform generator, this sweeps frequency and plots gain and phase automatically. For anyone designing filters or checking feedback loops, it is a huge time saver.
• Built-in waveform generator. Models with an “S” suffix (DHO914S, DHO924S, DS1074Z-S, DS1104Z-S) include a function generator. This removes a separate box from your bench, though the built-in generator is usually modest — typically one or two channels and tens of MHz.
• Remote control and screen capture. All current Rigol scopes support SCPI over USB and typically LAN, plus a web interface on the DHO series for remote viewing and control. Being able to grab a screenshot to a PC without a USB stick is a small thing you will use constantly.
• Mask/limit testing, pass/fail, math channels, and reference waveforms. Less glamorous, occasionally essential.

12-Bit vs 8-Bit: The Biggest Generational Change in Budget Scopes

The single most consequential difference between Rigol’s older DS1000Z family and its current DHO family is the analog-to-digital converter. Traditional budget scopes use an 8-bit ADC, giving 256 vertical levels. The DHO series uses a 12-bit ADC, giving 4096 levels — sixteen times the vertical resolution.

Why this matters in practice: an 8-bit scope resolving a 3.3 V logic signal has a vertical step of about 13 mV. If you are looking at a 20 mV ripple riding on a 5 V rail, an 8-bit scope simply cannot show you the shape of that ripple — you are looking at quantization noise. A 12-bit scope resolves roughly 0.8 mV per step at the same range, so the ripple is visible as an actual waveform.

The trade-off is that 12-bit acquisition produces more data and the scope has to work harder to process it, which is one reason the DHO series uses a more powerful processing platform and a touchscreen interface. The other trade-off is price: a 12-bit scope of a given bandwidth costs more than an 8-bit one. Given that the DHO804 sits in roughly the same price bracket the DS1054Z occupied years ago, though, the 8-bit budget scope is increasingly hard to justify for a new purchase.

Bandwidth You Actually Need, by Project Type

Buying bandwidth you cannot use is wasted money; buying too little is a scope you outgrow in six months. Here is how common hobby projects map onto bandwidth requirements. These figures assume you want to see edges and ringing honestly, not just confirm that something is switching.

Two conclusions fall out of that table. First, 100 MHz with four channels covers the overwhelming majority of hobby electronics. Second, if you work on switching power supplies regularly, 200 MHz is worth paying for, because switch-node edges in modern converters are genuinely fast and a 100 MHz scope will round them off.

Bench Realities: Footprint, Noise and What Wears Out First

Specifications do not tell you whether a scope fits on your desk. A few practical numbers.

Footprint. The DHO800 series is the compact option: roughly 26–27 cm wide, 15–16 cm deep and about 6–8 cm tall, weighing in the region of 1.5–2 kg. That fits on a shelf or in a drawer. The DHO900 and DHO1000 series with 10.1-inch displays are closer to 34–36 cm wide and 3–4 kg — still manageable, but it will occupy a permanent spot on your bench rather than living in a cupboard. The MSO5000 series is a larger, deeper chassis with a bigger power supply, and it is a fixture, not a portable.

Clearance. Leave at least 10 cm behind the instrument for the fan exhaust and cable bend radius, and 15 cm on the right or left depending on which side your USB ports are. Probes are the real space hog: a 10:1 passive probe with its ground lead is roughly 1.2 m long, and the ground clip lead is typically 15–20 cm. If your bench is 60 cm deep, you will spend most of your time fighting probe leads. A 75 cm depth is a much more comfortable minimum.

Noise. Every one of these instruments has a cooling fan. Small scopes are generally quiet, in the range of a low hum you stop noticing; larger chassis with bigger power dissipation are louder. None of them are silent, and none of them are loud enough to be a problem in a normal room.

Warm-up drift. Allow 15–30 minutes of warm-up before trusting vertical accuracy or doing anything where you compare absolute levels. Budget scopes drift noticeably in the first few minutes after power-on. This is normal and not a defect.

What wears out first. In rough order of likelihood on a hobby bench: the probe tips and ground leads (the most common failure, and cheap to replace); the rotary encoders and knobs, which get dirty and become jumpy after years of use; the cooling fan, which develops bearing noise and eventually needs replacement; the LCD backlight, which dims over many thousands of hours; and finally the power supply capacitors, typically the first internal component to fail after a decade. The instrument itself is usually the last thing to break — scopes from the DS1000Z era are still in service. Firmware updates matter more than hardware durability for staying useful.

The Picks, Model by Model

Rigol DHO802 — the cheapest genuinely modern Rigol

The DHO802 is the entry point to the DHO family: 70 MHz of bandwidth, two analog channels, a 12-bit ADC, up to 1.25 GSa/s sampling, 25 Mpts of memory and a 7-inch 1024×600 capacitive touchscreen. It typically sells in the $300–$350 range, which makes it the least expensive way to get a 12-bit front end and a modern interface from Rigol.

What you get for the money is a scope that feels current. The touchscreen is responsive, the web interface works, and the 12-bit ADC gives you small-signal detail that an 8-bit scope at the same price cannot match. For audio work, sensor conditioning, power-rail inspection and slow digital signals, 70 MHz is plenty — remember that a 70 MHz scope comfortably shows edges down to about 5 ns.

What you give up is channels and headroom. Two channels rules out SPI decode and makes three-phase or half-bridge work impossible. And 70 MHz will round off fast switch-node edges in a modern SMPS, which matters if power electronics is your main interest. If neither of those applies to you, the DHO802 is excellent value and a genuinely capable first scope.

Rigol DHO804 — the best value in the lineup

The DHO804 is the DHO802 with two more channels. Same 70 MHz bandwidth, same 12-bit ADC, same 1.25 GSa/s, same 25 Mpts, same 7-inch touchscreen. The price typically lands in the $400–$500 range — a premium of roughly $100–$150 over the two-channel version.

That premium buys you the ability to look at an SPI bus properly, to watch a motor driver’s three phases, to trigger on one signal while monitoring two others, and to keep two channels free for differential measurements. It also means that when you inevitably want to debug something with four signals, you do not have to buy a second instrument.

The honest limitation is bandwidth. 70 MHz is fine for microcontrollers up to roughly 50–70 MHz clocks, fine for audio and fine for slow power supplies, but it is tight for a modern SMPS switch node or a fast logic edge. If you can stretch to the DHO814, do; if you cannot, the DHO804 is the better purchase than any 100 MHz two-channel scope at the same price.

Rigol DHO812 — 100 MHz with two channels

The DHO812 steps the bandwidth up to 100 MHz while staying at two channels, typically in the $450–$550 range. It is the right answer only for a narrow set of buyers: someone who needs the extra 30 MHz of edge fidelity and is certain they will never need more than two simultaneous signals. Single-channel probing, audio characterization, and simple input-versus-output comparisons all fit that description.

For most hobbyists, though, the DHO812 sits in an awkward spot. It costs roughly the same as the four-channel DHO804 and gives you less capability overall. Unless two channels is a deliberate, permanent constraint, the DHO804 or DHO814 is the better use of the same money. Consider the DHO812 if you already own a four-channel scope and want a compact second instrument for single-signal work.

Rigol DHO814 — the best overall hobbyist Rigol

The DHO814 is where the lineup makes sense. It gives you 100 MHz of bandwidth, four analog channels, a 12-bit ADC, up to 1.25 GSa/s sampling, 25 Mpts of memory and the 7-inch touchscreen, usually for somewhere in the $600–$750 range.

Why this is the pick: 100 MHz covers essentially every common hobby project with margin, four channels covers SPI, three-phase, and trigger-plus-cause-plus-effect measurements, and the 12-bit converter makes the scope useful for audio and small-signal work in a way 8-bit instruments are not. Remember the probe caveat — the bundled 10:1 probes mean the practical system bandwidth is lower than 100 MHz, so having the extra headroom over a 70 MHz model is worth more than the number suggests.

The main trade-offs are memory depth and sample rate. 25 Mpts at 1.25 GSa/s gives roughly 20 ms of full-rate capture, which handles a full I²C transaction or a short UART frame but not a long boot sequence at full resolution. If you routinely need to capture tens of milliseconds at full sample rate, look at the DHO1000 series instead. And when all four channels are active, the per-channel sample rate drops, which is normal but worth remembering.

Rigol DHO914S — 125 MHz, four channels, with a built-in generator

The DHO914S moves up to the larger platform: 125 MHz of bandwidth, four channels, a 12-bit ADC, 50 Mpts of memory and a 10.1-inch 1280×800 touchscreen, typically in the $1,100–$1,400 range. The “S” suffix means it includes a built-in two-channel waveform generator, and with it the Bode plot function that sweeps a circuit’s frequency response automatically.

The bigger screen is not a cosmetic upgrade. Four traces, a measurement table, a decode list and a menu on a 7-inch 1024×600 panel is cramped; on a 10.1-inch 1280×800 panel it is comfortable. Doubling the memory to 50 Mpts also gives you roughly 40 ms of full-rate capture at 1.25 GSa/s, which handles multi-frame serial bursts and motor startup events that the 25 Mpts models struggle with.

The built-in generator is the reason to choose the “S” variant over the plain DHO914. It is modest — do not expect lab-grade performance — but it eliminates a separate box and enables the Bode plot workflow. If you design or tune filters, check feedback loop stability, or characterize speakers and audio circuits, that single feature justifies the premium. If you already own a function generator, the non-S version is the better buy.

Rigol DHO924 — 250 MHz on the mid-range platform

The DHO924 keeps the four channels, the 12-bit ADC, the 50 Mpts of memory and the 10.1-inch touchscreen but raises bandwidth to 250 MHz, typically in the $1,200–$1,500 range. At 250 MHz you can see edges down to roughly 1.4 ns, which covers fast logic, high-speed gate drivers, and the switch nodes of essentially any hobby-accessible power converter.

This is the model to consider if your interests lean toward power electronics or fast digital rather than audio and microcontrollers. The 250 MHz front end, combined with 50 Mpts of memory, lets you capture a fast edge and the slow envelope around it in a single acquisition — a combination that cheaper scopes force you to choose between.

The trade-off is that 250 MHz of analog front-end bandwidth with a shared 1.25 GSa/s converter is a stretch when all four channels are active, and the instrument is physically larger than the DHO800 series. For a small apartment bench, the size difference is worth thinking about before you buy.

Rigol DHO924S — the fully loaded mid-range option

The DHO924S is the DHO924 with the built-in waveform generator and Bode plot capability, typically around $1,500–$1,900. It combines 250 MHz, four channels, 12-bit resolution, 50 Mpts of memory, a 10.1-inch touchscreen and an integrated signal source in one chassis.

This is the model that consolidates a bench. If you were planning to buy a 200–250 MHz scope plus a separate function generator, the combined price is often close to what the DHO924S costs, and you get one instrument with one power supply, one screen and one set of controls instead of two boxes and a tangle of BNC cables. For someone building out a first serious bench in a small space, that consolidation is worth a lot.

Where it stops making sense is if you already own a good generator, or if your work never needs a swept frequency response. In that case, the plain DHO924 or the DHO814 frees up budget for probes and accessories that will improve your measurements more than the extra generator would.

Rigol DHO1074 — 70 MHz with deep memory and a fast converter

The DHO1074 sits on the DHO1000 platform: 70 MHz, four channels, 12-bit ADC, up to 2 GSa/s sampling, 100 Mpts of memory and a 10.1-inch 1280×800 touchscreen, usually in the $1,300–$1,700 range. Notice the shape of that specification — low bandwidth, high sample rate, enormous memory. It is the inverse of what most people expect from a premium scope.

That shape is deliberate, and it is exactly right for a specific job: capturing long, complex events at high resolution. At 2 GSa/s with 100 Mpts you get about 50 ms of full-rate capture, which swallows a complete device boot sequence, a long protocol exchange or a slow sensor ramp without dropping the sample rate and losing the fast edges embedded inside it. For embedded developers debugging startup behavior, this is transformative.

What it is not is a fast scope. 70 MHz will round off modern switch-node edges, and if you mainly chase fast transients, the DHO924 at 250 MHz is the better tool despite having less memory. The DHO1074 is a specialist’s instrument that happens to be priced within hobbyist reach — buy it for the memory, not for the bandwidth.

Rigol DHO1204 — 200 MHz with deep memory

The DHO1204 is the balanced member of the DHO1000 family: 200 MHz, four channels, 12-bit, 2 GSa/s, 100 Mpts and the 10.1-inch touchscreen, typically in the $2,200–$2,800 range. It fixes the DHO1074’s bandwidth limitation without giving up the memory or the sample rate.

At this price it is no longer an impulse purchase, and it is well past what most hobbyists need. But if you are doing serious power electronics, precision analog design, or embedded work where you need both fast edges and long captures, the combination of 200 MHz, 2 GSa/s and 100 Mpts is genuinely hard to beat at the price. This is the model to buy when you have decided the scope is a long-term instrument rather than a first purchase.

Consider carefully whether you are buying capability you will use. Many hobbyists who buy at this tier would have been equally well served by a DHO814 plus a good bench power supply and a decent function generator — three tools that cover more ground than one very capable scope.

Rigol MSO5074 — mixed-signal for microcontroller work

The MSO5074 is a different animal: 70 MHz, four analog channels plus 16 digital logic channels, an 8-bit ADC, up to 8 GSa/s sampling and 200 Mpts of memory, with a 9-inch touchscreen, typically in the $1,100–$1,500 range. The bandwidth is also upgradeable via license, which is unusual and worth knowing about.

The 16 digital channels are the point. Instead of squinting at analog traces to decide whether a data line is high or low, you get a proper timing diagram with the analog channels aligned above it, and the serial decode can show you the actual bytes. For anyone spending their weekends on microcontroller buses, address lines or parallel interfaces, this is a qualitatively different workflow — not just more of the same.

The trade-offs are real. It is 8-bit, so small-signal analog detail is worse than any DHO model. It is physically large and heavy. And although the 8 GSa/s headline is impressive, it is an interleaved figure that drops substantially with more channels enabled. The MSO5074 is the right scope for a digital-focused hobbyist and the wrong one for an audio-focused hobbyist, and no amount of specification comparison changes that.

Rigol MSO5104 — 100 MHz mixed-signal

The MSO5104 raises the MSO5074’s bandwidth to 100 MHz while keeping four analog channels, 16 digital channels, 8 GSa/s and 200 Mpts of memory, typically in the $1,500–$1,900 range. The bandwidth upgrade matters because 70 MHz is genuinely tight for modern microcontroller clocks and fast SPI, and the extra 30 MHz makes the difference between a usable and a marginal instrument for 100 MHz-class digital work.

If you have decided you need a mixed-signal scope, this is generally the better choice over the MSO5074 unless the price difference is decisive. The analog performance is otherwise identical, and the additional bandwidth directly addresses the most common complaint about the lower model. Both remain 8-bit instruments, so neither is a good choice if precision analog measurement is part of your plan.

Rigol DS1054Z — the classic, now a used-market question

The DS1054Z is the scope that defined budget hobby electronics for years: 50 MHz, four channels, 1 GSa/s, 24 Mpts of memory, an 8-bit ADC and a 7-inch 800×480 non-touch display, historically around $350–$500 new. It earned its reputation honestly — four channels at a price that used to buy two, with a then-excellent memory depth.

In 2026 it is a legacy choice. The DHO804 costs about the same, has four channels, a 12-bit converter, a faster interface and a touchscreen. Against that comparison, the DS1054Z’s only remaining advantages are a well-understood firmware ecosystem, a huge base of existing documentation and community knowledge, and the fact that used units change hands cheaply.

If you find one in good condition at a genuinely low price, it is still a capable instrument and there is nothing wrong with it. But as a new purchase at full retail, it no longer makes sense. The 8-bit limitation and the non-touch interface are not deal-breakers individually, but together they put it a generation behind at a similar price. Its bandwidth is also upgradeable by license, which is worth checking if you buy used.

Rigol DS1104Z and DS1104Z-S — 100 MHz on the older platform

The DS1104Z brings 100 MHz, four channels, 1 GSa/s and 24 Mpts of memory to the DS1000Z platform, typically $700–$1,000 depending on configuration. The DS1104Z-S adds a built-in two-channel waveform generator for a few hundred dollars more.

The problem is the comparison: at that price, the DHO814 gives you the same bandwidth and channel count, a 12-bit ADC instead of 8-bit, a touchscreen instead of encoders, and a more modern processing platform. The only reason to choose the DS1104Z-S is if the built-in generator is central to your work and you prefer the DS platform’s generator implementation — but the DHO914S exists for exactly that use case, with better analog performance.

These models remain in the catalog and remain competent. They are simply no longer the value proposition they were, and they make sense primarily for buyers who specifically want the older, knob-driven interface or who find a discounted unit.

Rigol DS1202Z-E — 200 MHz on a budget, two channels

The DS1202Z-E is the outlier worth knowing about: 200 MHz of bandwidth, two channels, 1 GSa/s, 24 Mpts of memory and an 8-bit ADC, typically in the $500–$700 range. It is the least expensive way to get 200 MHz from Rigol, and at 200 MHz you can see edges down to roughly 1.75 ns.

This is a specialist’s scope for someone who needs fast edges and does not need many channels. Think single-channel signal integrity work, fast logic characterization, or checking the rise time of a driver output. For that narrow purpose it is excellent value, because bandwidth is the expensive specification and this model trades channels to buy it.

For general hobby electronics it is the wrong shape: two channels rules out SPI and most multi-signal debugging, and the 8-bit ADC limits small-signal work. Buy it as a complement to a four-channel scope, or as a first scope only if you are certain your work is single-signal and fast.

Models to know about but probably skip

Rigol’s higher tiers — the DHO4000 series, the MSO7000 series and the DS7000 series — offer bandwidths from 200 MHz into the GHz range with proportionally higher prices, typically several thousand dollars and up. They are excellent instruments and they are not hobbyist purchases. Similarly, the older DS2000 and DS4000 families occasionally appear used at attractive prices; they are capable but predate the 12-bit generation and the modern interface, so evaluate them on the same terms as the DS1000Z family.

Decision Matrix: Match Your Situation to a Scope

Accessories: Where the Remaining Budget Should Go

A scope is only as good as what connects to it. The bundled probes on Rigol scopes are adequate for general work but are the first thing worth upgrading, and the accessories below typically improve measurement quality more per dollar than moving up a bandwidth tier.

The pattern: for roughly the price difference between a DHO804 and a DHO924, you can buy a decent bench power supply, a multimeter and a set of probes. If your bench currently has none of those, that is the better spend. A four-channel 70 MHz scope with good probes and a clean power supply will out-measure a two-channel 250 MHz scope with bad probes and a noisy USB charger.

Setup and First-Week Checklist

Once the scope arrives, a few steps prevent weeks of confusing measurements.

• Update the firmware first. Budget scopes ship with whatever firmware was current at the factory, and later versions routinely fix bugs, improve UI responsiveness and occasionally add features. Do this before you form an opinion about the instrument.
• Compensate every probe. Connect each probe to the scope’s built-in calibration output and adjust the trimmer until the square wave has flat tops. Do this once per probe, and redo it if you change the probe’s attenuation setting. An uncompensated probe will make you chase a nonexistent overshoot problem.
• Learn the memory-depth setting. Find where to switch between shallow (fast update) and deep (long capture) modes. Interactive probing wants shallow; one-shot captures want deep.
• Set up a ground reference discipline. Every probe’s ground clip is connected to mains earth through the scope. Do not clip it to anything that is not at earth potential. For floating measurements, use a differential probe or an isolation transformer — never lift the scope’s earth pin.
• Configure the network interface. The DHO series supports LAN and a web interface. Being able to pull screenshots to a PC and script the instrument over SCPI is worth the twenty minutes of setup.
• Write down your default setup. Most Rigol scopes let you save and recall configurations. Build one for your most common measurement and recall it instead of re-setting six things every session.
• Give it 15–30 minutes of warm-up before any measurement where absolute accuracy matters.

Frequently Asked Questions

Do I really need four channels?

If you work on microcontroller buses, motor drivers, or anything with more than two signals that need to be correlated in time, yes — and the price premium over two channels is usually only $100–$150. If your work is genuinely input-versus-output, two channels is fine and the money is better spent on bandwidth or accessories. The mistake is buying two channels to save money and then buying a second scope six months later.

Is 50 MHz or 70 MHz enough?

For audio, slow digital and basic microcontroller work, yes. For anything with a clock above about 50 MHz, modern SPI, or switching power supplies, no — you will see rounded edges and miss ringing. Treat 100 MHz as the comfortable floor for general hobby electronics and 200 MHz as the comfortable floor for power electronics.
