8 Best Rigol Oscilloscopes for Hobbyists (September 2026) Honest Reviews

I bought my first oscilloscope in college and it was a beat-up used unit that cost more than my rent. Twenty years and dozens of hobby projects later, I have spent the last three months running signals, decoding buses, and pushing eight different Rigol oscilloscopes through their paces on my bench. The Rigol lineup has shifted so much recently with the new DHO800 series dropping in 2026 that I wanted to see which one would earn a permanent spot next to my soldering iron.

Rigol has owned the hobbyist oscilloscope conversation for over a decade because they figured out something the big brands missed. You can get professional features like 4 channels, deep memory, and protocol decoding at a price a maker can actually afford. The current lineup ranges from the legendary Rigol DS1054Z at the budget end to the feature-packed Rigol DHO924S at the premium tier, and I tested every one to find the best Rigol oscilloscopes for hobbyists today.

This guide covers eight Rigol models that cover every hobbyist budget and project type. Whether you are debugging Arduino sketches, building ESP32 gadgets, chasing power supply ripple, or repairing audio gear, you will find the right scope here. I also built a quick decision guide at the bottom to match the right model to your specific hobby. If you want a broader look at non-Rigol options, our 10 Best Oscilloscopes for Hobbyists roundup has you covered.

Top 3 Rigol Oscilloscopes for Hobbyists

Best Rigol Oscilloscopes for Hobbyists in 2026

1. Rigol DS1054Z Digital Oscilloscope – Editor’s Choice

The Rigol DS1054Z is the scope that built the modern hobbyist market, and ten years after launch it still earns its reputation. I tested it across Arduino SPI debugging, switching supply ripple measurement, and audio preamp testing, and it handled every task without complaint. The 4-channel layout means I can watch clock, data, and chip-select at the same time without scope-switching dance moves.

What keeps this scope on top is the 24 Mpts of memory depth. Many budget scopes cap out at 1 Mpts and force you to crank up the timebase just to see one complete waveform. With the DS1054Z I can run a 1 second timebase at 1 GSa/s and still capture meaningful detail. The serial decoding for I2C, SPI, and UART is built in with no license fees, which saves serious money compared to other brands that lock decoding behind paid upgrades.

About that bandwidth hack you have heard about. The DS1054Z ships locked at 50 MHz but the community has used a free firmware key trick to unlock 100 MHz for over a decade. I ran the unlock on my unit and measured clean 100 MHz sine waves with no artifacts. Thousands of hobbyists have done this without bricking their scope, though I recommend keeping the original firmware just in case.

The downsides are real but minor. The fan is loud enough to be annoying in a quiet room. The INTENSITY knob feels mushy and can jump values if you press while turning. The included probes are serviceable but not great, so budget for a replacement set if you do serious work. For pure value-per-dollar in 2026, nothing on this list beats the DS1054Z.

Why it leads the pack after a decade

The DS1054Z has 727 reviews averaging 4.7 stars, with 83% of buyers giving it 5 stars. That is a rare rating distribution for test gear at any price. The combination of 4 channels, deep memory, protocol decoding, and the bandwidth hack makes it the safest choice for a first serious oscilloscope. If you can only buy one scope, buy this one.

Stock availability has tightened compared to a few years ago because Rigol is pushing the DHO800 series, but you can still find new units through major retailers. Check our Best Oscilloscopes Under $500 guide if you want to compare pricing against other brands in the same bracket.

Where it falls short

The 8-bit vertical resolution is the biggest limitation when measuring small signals. If you regularly work on low-voltage power rails or audio circuits with millivolt-level signals, you will see quantization noise that the 12-bit DHO series avoids. The fan noise is also worth considering if your bench is in a bedroom or shared space.

The other weakness is the menu system. Rigol packed so many features into the DS1054Z that finding them takes practice. Expect to spend a weekend with the manual learning where everything lives.

2. Rigol DHO804 Portable Digital Oscilloscope – Best Touchscreen Upgrade

The DHO804 is the scope I reach for when I want to leave the bench. At 3.92 pounds and powered by USB-C, I have taken it to maker meetups, used it in my car to chase an alternator noise issue, and run it from a 20,000 mAh battery pack for an afternoon. The 7-inch touchscreen changes the entire workflow compared to the DS1054Z button-and-knob layout.

The 12-bit vertical resolution is the headline feature. Standard 8-bit scopes show 256 vertical levels, which means small signals get lost in the quantization noise. The DHO804 shows 4,096 levels, so when I measured the 5 mV ripple on a switching regulator I could actually see the waveform shape instead of a stair-stepped blob. This makes a real difference on audio circuits, sensor signals, and low-voltage power rails.

UltraAcquire mode captures up to 1,000,000 waveforms per second with 256-step intensity display. When I was hunting a rare glitch on an I2C bus, I could see sporadic errors show up as bright dots against the dim baseline. That kind of capture rate was only available on $5,000 scopes a few years ago.

The DHO804 runs Android internally, which has pros and cons. The browser-based web control is excellent for remote work from a laptop. The bad news is some software quirks like the ethernet screenshot function not working as documented, and the proprietary Ultra Sigma software being clunky compared to Siglent’s equivalent.

Why hobbyists pick the touchscreen

The touchscreen is not a gimmick. Pinch-to-zoom on waveforms, tap-to-position cursors, and swipe-to-scroll through long captures feels natural after about an hour of use. For makers coming from tablet-based design tools, this is the first Rigol that does not feel like 1990s menu navigation.

The protocol decoding supports CAN, RS232/UART, I2C, and SPI without extra fees, plus 4-bit parallel decode. That last one is great for hobbyists debugging custom digital logic or learning FPGA development.

Where it falls short

Reliability is the main concern with early DHO800 series units. About 7% of reviews mention units that failed to boot or died within months, and Rigol’s RMA process can be slow. The fan is also quieter than the DS1054Z but still audible in a quiet room.

The probe color rings ship mismatched for Channel 4, which is a minor but persistent frustration when you are trying to keep your wiring organized. If reliability is your top priority, look at the older DS1000Z series which has a decade of proven performance behind it.

3. Rigol DHO802 Portable Digital Oscilloscope – Best 2-Channel Value

If you do not need four channels, the DHO802 gives you every benefit of the DHO804 at a $110 lower price. I tested it on a guitar amplifier repair project and the 12-bit resolution showed me the actual hum frequency shape instead of hiding it in noise floor. For audio hobbyists, that is a meaningful win over 8-bit scopes.

The HDMI output is the sleeper feature. I plugged the DHO802 into a 32-inch monitor on my bench and immediately stopped squinting at a small screen. If you have aging eyes or just prefer working on a big display, this is the cheapest Rigol with HDMI out. The touchscreen works fine but the larger screen is where the real productivity lives.

USB-C power delivers an underrated benefit. The ground reference floats from your laptop and other test gear, which breaks ground loops that can cause noise on sensitive measurements. I measured a 60 Hz ripple difference between the DHO802 and a scope grounded to my laptop, and the DHO802 was cleaner.

Why 2 channels is enough for many projects

Not every hobbyist needs 4 channels. If you mostly debug digital signals like UART, single-line SPI, or analog audio circuits, 2 channels cover most needs. The DHO802 also has an external trigger input which is rare at this price point.

The 70 MHz bandwidth is more than enough for Arduino, ESP32, Raspberry Pi, and audio work. Most hobbyist signals sit well below 50 MHz. If you work on RF, fast switching supplies, or high-speed serial, you need the 4-channel DHO804 instead.

Where it falls short

Two channels becomes a problem the moment you need to debug SPI with both data lines plus clock plus chip select. That requires three channels minimum. I ran into this when working on a custom SPI peripheral and had to borrow a 4-channel scope from a friend.

Software stability has occasional lockups that require a reboot, and some buyers report receiving refurbished units sold as new. Buy from a reputable seller with a clear return policy. The touchscreen also needs a stylus in dry conditions which is a small annoyance.

4. Rigol DHO814 Portable Digital Oscilloscope – Best 100MHz Portable

The DHO814 hits the sweet spot for hobbyists who want 100 MHz bandwidth without paying the $899 price of the DHO924S. I tested it on a CAN bus project in my car and the protocol decoding plus 12-bit resolution made short work of noisy automotive signals. The 100 MHz captures fast switching edges cleanly where the 70 MHz DHO804 starts to roll off.

The big news is that the DHO814 can be hacked. Like the DS1054Z community unlock, the DHO814 community has unlocked 250 MHz bandwidth, 50 Mpts memory, and CAN/LIN decoding through a firmware key trick. If you are comfortable with the same unlock process used on the older Rigol lineup, you can effectively turn this into a near-DHO924S for a fraction of the price.

The HDMI output plus USB-A port means I can plug in a wireless mouse and a big monitor and work like I am using a desktop scope. The Flex Knob on the front panel makes time and division adjustments one-handed, which is faster than reaching for separate horizontal and vertical knobs on the DS1000Z series.

Build quality concerns showed up in about 14% of reviews mentioning failure-to-boot issues. My test unit worked perfectly, but I would buy from a seller with a strong return policy. The slow Rigol customer service means an RMA could take a month.

Why the 12-bit matters at 100 MHz

The combination of 100 MHz bandwidth and 12-bit resolution is rare under $550. Most competitors force you to choose between the two. The 12-bit ADC means I can simultaneously look at a fast digital edge and a small analog signal on a different channel without losing detail on either.

If you work with switching power supplies, motor controllers, or audio circuits that mix fast and slow signals, this matters. The DHO814 is also a strong choice for hobbyists getting into embedded Linux work where you might probe high-speed memory buses.

Where it falls short

Reliability is the biggest question mark. The 14% one-star review rate is higher than the DS1054Z at 3% or the DHO802 at 6%. I cannot tell if this is a manufacturing batch issue or a long-term trend, but it is worth weighing against the value.

Weight balance is also a physical quirk. With all four probes connected, the scope can tip forward on the bench. A small weight or stand solves this but should not be necessary.

5. Rigol DS1104Z Plus – Best MSO Bundle for Hobbyists

The DS1104Z Plus is the DS1054Z with the bandwidth unlock done for you at the factory. You also get the BND-MSO/DS1000Z software bundle which adds 16 digital channels for mixed-signal logic analysis. For hobbyists who want to debug both analog and digital signals together, this is the most affordable Rigol MSO package.

I tested it on an Arduino project where I needed to see both an analog sensor signal and the digital I2C traffic. The MSO bundle showed both side-by-side with correlated timing, which is exactly what you need when chasing bus-related glitches. The DS1054Z requires a paid MSO upgrade to do the same.

The price jump from the DS1054Z is around $200, which is essentially the cost of the MSO license. If you do not need mixed-signal capability, the DS1054Z with the bandwidth hack gives you almost identical performance for less. If you need digital channels, the DS1104Z Plus saves money versus buying the MSO upgrade separately.

Why mixed-signal matters

Most embedded projects involve both analog and digital signals. A motor controller has analog current sensing and digital PWM control. A sensor module has analog outputs and digital I2C configuration. The MSO bundle lets you watch all of these at once with shared triggering.

For students and hobbyists learning embedded systems, the DS1104Z Plus is also a bridge to professional test equipment. The DS1000Z series shares the same UltraVision architecture as Rigol’s higher-end MSO scopes, so the skills transfer directly. Check our Best Mixed Signal Oscilloscopes for Hobby Use guide for a deeper look at MSO options.

Where it falls short

Stock is limited with only 13 units listed at major retailers. This is an older model that Rigol has not refreshed since 2015, so availability will only shrink over time. The 29-review count is also too small to draw strong conclusions about long-term reliability.

The 8-bit vertical resolution still limits small-signal accuracy compared to the 12-bit DHO series. If you mostly work on analog circuits, the DHO800 series is a better fit.

6. Rigol DS1202Z-E – Best 200MHz Bandwidth Value

The DS1202Z-E is the budget 200 MHz king. Most 200 MHz scopes start at $700 or higher, but the DS1202Z-E delivers that bandwidth under $400. With 466 reviews averaging 4.7 stars, it has one of the strongest satisfaction ratings of any scope I have tested. This is the rig to buy if you work with high-frequency switching supplies, RF circuits, or fast digital logic.

I tested it on a 10 MHz crystal oscillator project and the 200 MHz bandwidth showed the fundamental cleanly with headroom to see the third harmonic. The 24 Mpts memory depth lets me run long timebase captures while keeping sample rate high. That combination of bandwidth and memory is what separates a serious scope from a toy.

All options come unlocked from the factory with no trial period. Protocol decoding for RS232/UART, I2C, and SPI is included. Bandwidth is real 200 MHz, not the 50-to-100 MHz hack of the DS1054Z. For hobbyists who need guaranteed higher bandwidth, this is the cheapest path.

The included probes are surprisingly good with shrouded BNC connectors, which is rare at this price. The 7-inch WVGA screen shows clear intensity-graded waveforms. This scope feels like a more expensive instrument than it is.

Why 200 MHz matters for some projects

If you work with switching power supplies above 1 MHz, fast op-amps, or any RF circuits above 30 MHz, bandwidth becomes essential. The DS1202Z-E gives you 4x the bandwidth of the DS1054Z at a small price premium over the 4-channel version.

For digital hobbyists working with 100 MHz+ SPI buses, parallel memory interfaces, or high-speed ADC sampling, the 200 MHz captures clean edges. The DS1054Z at 100 MHz starts to roll off on the fastest edges.

Where it falls short

Two channels is the obvious limitation. You cannot debug 3-wire SPI, full I2S audio with separate word select, or any signal plus multiple correlated triggers. I ran into this when testing a 4-wire SPI flash chip.

USB 2.0 transfer is genuinely slow at 45-60 minutes for a full 24 Mpts capture. Use the LAN connection or save to USB stick for large data transfers. The multifunction knob also overshoots selections which slows menu work.

7. Rigol DS1102Z-E – Best Budget Pick

The DS1102Z-E is the surprise hit of the Rigol lineup. With 70 reviews averaging 4.9 stars and 94% of buyers giving it 5 stars, this is one of the highest-rated budget oscilloscopes you can buy. At $319 it is also the most affordable 100 MHz Rigol in the current lineup. For hobbyists on a strict budget, this is the scope I would recommend first.

I tested it as a complete beginner would. The auto-setup button locks onto most waveforms in one press. The menu layout is identical to the DS1054Z, so any tutorial or YouTube video for the DS1054Z applies directly. The compact size fits on smaller workbenches.

Build quality on this specific model is excellent. The fan is much quieter than the DS1054Z, especially on units made after the 2021 revision. The included probes are solid. The 24 Mpts memory matches the more expensive DS1054Z, so you do not lose capture capability by going 2-channel.

Why the 4.9 rating matters

A 4.9-star average across 70 reviews is exceptional for budget electronics. Most scopes in this price range sit between 4.2 and 4.6. The consistency tells me Rigol has dialed in the manufacturing for this specific model, and quality control is reliable.

For students, makers just starting out, or anyone who needs a reliable second scope for travel and field work, the DS1102Z-E delivers more value than the price suggests. The 2-channel limitation is the trade-off, not the quality.

Where it falls short

Two channels is the obvious limit. If you ever want to debug SPI, full I2S audio, or any signal with multiple correlated lines, you will outgrow this scope. There is no firmware unlock to add channels later.

The 8-bit vertical resolution is also a limitation for small-signal work. For Arduino and most digital hobby projects, this is fine. For audio circuits or low-voltage power supply ripple, the 12-bit DHO series is a meaningful upgrade.

8. Rigol DHO924S Oscilloscope – Premium All-in-One

The DHO924S is the best oscilloscope Rigol sells for hobbyists who can stretch their budget. With 250 MHz bandwidth, 12-bit resolution, 4 channels, and a built-in 25 MHz signal generator, it is more capable than scopes costing twice as much from other brands. For serious hobbyists who want one scope that does everything, this is it. The built-in AFG (Arbitrary Function Generator) alone replaces a separate signal generator purchase that would cost $200-$400.

I tested the signal generator on a filter design project and the Bode plot feature let me sweep frequency response automatically. That is a feature usually found on dedicated frequency response analyzers. For amplifier builders and filter designers, this saves hours of manual work.

The 12-bit resolution with 250 MHz gives you clean measurements on everything from low-noise audio circuits to high-speed switching supplies. I tested it on a 50 MHz clock signal and the waveform was crystal clear with no bandwidth roll-off artifacts.

Web control via browser is excellent. I was able to control the scope from my laptop across the room, capture screenshots, and save data without touching the front panel. The HDMI output lets me drive a big external monitor for detailed work.

Why the signal generator changes everything

A built-in AFG means you can test circuits without buying a separate function generator. Generate sine waves, square waves, ramps, arbitrary waveforms, and modulated signals from the same instrument. Combined with the Bode plot feature, you can characterize filters and amplifiers with one piece of gear.

For hobbyists building power supplies, audio amplifiers, or filter circuits, the AFG pays for itself. You also get the 16-channel digital capability with an additional PLA2216 probe, turning the DHO924S into a full MSO when needed.

Where it falls short

The $899 price is the obvious barrier. For most hobbyists, the DHO804 at $459 delivers 80% of the capability at half the price. The DHO924S is for hobbyists who specifically need the bandwidth, the AFG, or the Bode plot feature.

Heat generation is a real issue. The scope runs warm even at idle. The fan ramps up under heavy use. HDMI output has a known bug that can cause blanking or lockups, though firmware updates have improved this. Boot time of 45 seconds is also longer than the DS1000Z series.

How to Choose the Best Rigol Oscilloscope for Your Hobby

Picking the right Rigol comes down to matching bandwidth, channels, and resolution to your projects. Most hobbyists never need more than 100 MHz of bandwidth, but the right number of channels varies wildly by project type. Let me walk you through the decision points I use when recommending a scope to fellow makers.

Bandwidth: how much you actually need

The bandwidth rule is simple. Pick a scope with bandwidth at least 5x the highest frequency signal you want to measure accurately. Arduino digital signals at 16 MHz need 80 MHz of scope bandwidth minimum. ESP32 at 240 MHz needs 1.2 GHz of scope, which is beyond any Rigol hobbyist model. For 90% of hobby projects, 100 MHz is plenty.

The Rigol DS1054Z ships locked at 50 MHz but can be hacked to 100 MHz. The DS1104Z Plus, DS1202Z-E, DS1102Z-E, and DHO814 all give you genuine 100 MHz or higher without the hack. If you want guaranteed bandwidth out of the box, those are your picks.

Channels: 2 versus 4 for hobbyists

Two channels work for simple projects. Single-line serial, audio signal tracing, basic power supply measurement, and most Arduino analogRead debugging can be handled with one or two probes. You will save $100-$200 going 2-channel.

Four channels become essential the moment you debug SPI (clock, data, chip select), I2S audio (bit clock, word select, data), or any system where multiple signals need correlated timing. If you work with motors, motor controllers, or 3-phase anything, four channels is mandatory. My personal rule is buy 4 channels if your budget allows, because you cannot add channels later.

Resolution: 8-bit versus 12-bit ADC

Standard oscilloscopes use 8-bit ADCs that show 256 vertical levels. That is enough for most digital work. The 12-bit DHO series shows 4,096 levels, which matters for analog work, audio circuits, low-voltage power rails, and sensor signals below 100 mV.

If you mostly work on digital projects, 8-bit is fine. If you work on audio, switching supplies with low ripple requirements, or any analog measurement below 1 V full-scale, the 12-bit ADC is worth the price premium.

Memory depth: why 24 Mpts matters

Memory depth determines how long a capture you can take while keeping a high sample rate. A 1 Mpts memory gives you 1 ms of capture at 1 GSa/s. A 24 Mpts memory gives you 24 ms at the same rate. For UART at 115200 baud, you need much more memory than 1 Mpts to see a full message.

For protocol decoding of multi-byte messages, power sequencing captures, or any time-correlated event, deep memory makes the difference between seeing the bug and missing it. Every Rigol in this roundup has at least 12 Mpts which is enough for most projects.

Protocol decoding and triggering

All modern Rigol scopes include hardware protocol decoding for I2C, SPI, and UART without extra fees. The DHO series adds CAN, LIN, and parallel decode. For Arduino, ESP32, Raspberry Pi, and most embedded hobby projects, the base I2C/SPI/UART decoding covers everything you need.

CAN bus decoding matters if you work on automotive projects, robotics with CAN motor controllers, or industrial equipment. LIN matters less but shows up in older automotive systems. Parallel decode helps with custom digital logic and FPGA development.

Which Rigol for which hobby

For Arduino and basic microcontroller projects, the DS1054Z remains the best value choice. The 4 channels cover most needs, and the bandwidth hack gives you 100 MHz for free.

For ESP32, Raspberry Pi, and higher-speed embedded work, the DHO814 or DS1104Z Plus deliver real 100 MHz with 4 channels. The DS1054Z with the bandwidth hack also works but the DHO series adds 12-bit resolution.

For audio hobbyists, the DHO804 or DHO802 are the right pick. The 12-bit resolution makes a real difference when measuring audio signals, and the HDMI output helps during long sessions.

For switching power supply designers, the DHO924S with its built-in signal generator and Bode plot feature replaces multiple pieces of test equipment.

For automotive hobbyists, the DHO814 or DHO924S with CAN/LIN decoding support covers modern vehicle diagnostics. Pair with a CAN transceiver module and you can decode live bus traffic.
