The Rivalry — And Why It Matters

Rigol and Siglent are the AMD and Intel of hobbyist oscilloscopes. Both are Chinese manufacturers that deliver professional-grade features at hobbyist prices, both have dedicated communities, and forum debates about which is better can get surprisingly heated. The short answer: both make excellent scopes, and the best choice depends on your specific needs, budget, and which features matter most to you. This guide breaks down the real differences so you can make an informed decision without wading through brand tribalism. I've used both brands extensively and I'll give you the honest picture, including where each brand falls short.

Software and Interface: Rigol's Touchscreen vs Siglent's Buttons

Rigol's new DHO series (DHO804, DHO924S) runs a modern phone-like touchscreen interface. It's intuitive, responsive, and has almost no learning curve. Pinch to zoom on a waveform, tap to place a cursor, swipe to scroll — if you can use a smartphone, you can navigate the DHO interface. Siglent's interface is more traditional and button-focused. It's functional and logical once you learn it, but it feels more like laboratory equipment than consumer electronics. Power users often prefer Siglent's physical buttons because they're faster once you know the layout. Beginners tend to prefer Rigol's touchscreen. The older Rigol DS1000Z series (DS1054Z, DS1104Z-S Plus) uses the same traditional button interface as Siglent — so if you're comparing DS1054Z vs SDS1202X-E, the interface difference is much smaller. For remote control and automation, both support SCPI commands via USB or LAN. Siglent's EasyScope software provides decent remote viewing. Rigol's Ultra Sigma is adequate. Neither is exceptional for programmatic control at the hobbyist price tier.
Pick #2

Rigol

Rigol DHO924S

$449

9.0/ 5
250 MHz4 ch50 Mptsbenchtop

Why we like it

The Rigol DHO924S is the best hobbyist oscilloscope under $500 in 2026, and I say that having used the DS1054Z for years before switching. The 7-inch IPS touchscreen transforms the experience — pinch to zoom, tap to place cursors, swipe to scroll through captures — in a way that button-based scopes simply can't match. Add 250MHz bandwidth, 4 channels, 50Mpt memory, a function generator, WiFi, and CAN/LIN protocol decoding at $449, and it obsoletes the DS1054Z in every spec column except community documentation and proven long-term reliability. If you're buying a scope in 2026 and can spend $449, this is the one to get. The only reasons to look elsewhere: you need deeper memory (Siglent SDS2104X Plus), you want proven track record over specs (DS1054Z), or you need CAN/LIN included free and can save $30 (Siglent SDS1104X-U at $419).

Pick #3

Siglent

Siglent SDS1202X-E

$379

7.5/ 5
200 MHz2 ch14 Mptsbenchtop

Why we like it

The Siglent SDS1202X-E is the DS1054Z's biggest competitor, and it wins on raw specs: 200MHz bandwidth, 14Mpt memory, and protocol decoding that includes CAN and LIN without paying for licenses. The catch is you only get 2 channels, and that trade-off matters more than it sounds. When you're debugging SPI with clock, data, and chip-select lines all running, or trying to correlate an analog signal with a digital trigger, you'll wish you had 4 channels. If you work primarily with audio circuits, RF signals, or single-channel measurements, the 200MHz bandwidth is genuinely useful and this scope makes complete sense. For general embedded debugging with multiple signals, I'd take the DS1054Z's 4 channels over the extra bandwidth.

Protocol Decoding: Siglent's Clear Advantage

This is where Siglent has a meaningful edge. Siglent includes SPI, I2C, UART, CAN, and LIN decoding standard on most models — no license fees, no activation codes, no upselling. Rigol's story is more complicated. The DHO series includes SPI, I2C, and UART, but CAN and LIN decoding are paid license options on most Rigol models. On the older DS1000Z series, basic decoding is included, but CAN requires a paid license that can cost $30-100. If you need CAN bus decoding for automotive work or industrial protocol analysis, Siglent wins this category cleanly. The SDS1104X-U at $419 includes CAN and LIN free — the equivalent Rigol capability costs noticeably more once you add the license. For general hobbyist use (SPI, I2C, UART), both brands are equivalent.
Pick #4

Siglent

Siglent SDS1104X-U

$419

7.5/ 5
100 MHz4 ch14 Mptsbenchtop

Why we like it

The Siglent SDS1104X-U is Siglent's answer to the 4-channel mid-range market, and its CAN/LIN decoding is its killer differentiator. Rigol charges extra for CAN decoding on most models; Siglent includes it free. If you're doing automotive embedded work — car CAN bus debugging, LIN network analysis, anything that touches vehicle electronics — the SDS1104X-U at $419 is the most cost-effective path to proper protocol support. For general hobbyist use without automotive protocol requirements, the DS1054Z at $349 remains better value, and the Rigol DHO924S at $449 offers 250MHz bandwidth and a touchscreen for just $30 more. I'd buy the SDS1104X-U specifically if CAN/LIN decoding is non-negotiable.

Rigol

Rigol DS1054Z

$349

8.5/ 5
50 MHz4 ch12 Mptsbenchtop

Why we like it

The Rigol DS1054Z is the default recommendation in every electronics forum for a reason — it earned that reputation over a decade of consistent performance. Four channels, 12Mpt memory, comprehensive protocol decoding, and an absurd number of trigger types for ~$349 is a package that nothing in this price range matched for years. The 50MHz bandwidth is the only real limitation, and the well-documented hack to unlock 100MHz makes even that a manageable concern. Yes, the newer Rigol DHO924S has better specs in nearly every category — but the DS1054Z has something no spec sheet can quantify: years of solved problems, answered questions, and tutorials from the EEVblog and r/AskElectronics communities. If you're buying your first serious oscilloscope and want to minimize frustration, this is still a great choice. If you can stretch to $449, the DHO924S is the better buy in 2026.

**Under $450 (mid-range):** | Rigol | Price | Siglent Equivalent | Price | |-------|-------|-------------------|-------| | DHO804 | $439 | (no direct equivalent) | — | | DS1054Z | $349 | SDS1202X-E | $379 | Rigol dominates here. The DHO804 has a 7-inch IPS touchscreen and 50Mpt memory at $439 — nothing from Siglent comes close for the interface. The DS1054Z vs SDS1202X-E comparison is close: DS1054Z wins on channels (4 vs 2) and community; SDS1202X-E wins on bandwidth (200 vs 50MHz) and CAN/LIN decoding. **$400-$800 (premium hobbyist):** | Rigol | Price | Siglent Equivalent | Price | |-------|-------|-------------------|-------| | DHO924S | $449 | SDS1104X-U | $419 | | — | — | SDS1204X-E | $775 | The DHO924S vs SDS1104X-U is the defining comparison in 2026. DHO924S wins on bandwidth (250 vs 100MHz), display (7-inch IPS touchscreen vs 7-inch non-touch), and overall usability. SDS1104X-U wins on CAN/LIN decoding at no extra cost and a lower price. If you need automotive protocol support, the SDS1104X-U at $419 is the better choice. For everything else, the DHO924S is the better scope. **$1,000+ (prosumer):** | Rigol | Price | Siglent | Price | |-------|-------|---------|-------| | (no direct competitor) | — | SDS2104X Plus | $1,099 | Siglent wins clearly with the SDS2104X Plus — 200Mpt memory, IPS touchscreen, comprehensive protocol decoding, built-in AWG. Rigol doesn't compete at this tier in the hobbyist market.

Pick #5

Siglent

Siglent SDS2104X Plus

$1099

8.0/ 5
100 MHz4 ch200 Mptsbenchtop

Why we like it

The Siglent SDS2104X Plus is a professional-grade scope that happens to be affordable enough for serious hobbyists, and using it for a long debugging session makes the price feel justified. The 200Mpt memory depth is the headline — you can capture minutes of data at full sample rate, then scroll back and zoom into any moment without re-triggering. The 10.1-inch IPS touchscreen is excellent. The comprehensive protocol decoding (including FlexRay and I2S) makes it the right tool for serious automotive or audio embedded work. The surprise is that all this comes with only 100MHz bandwidth — you're paying for depth, features, and build quality, not raw frequency response. At $1,099, this is a serious investment. It only makes sense if you do electronics work regularly enough to amortize that cost, and if you want an instrument you genuinely won't outgrow.

Community and Support: Rigol's Larger Presence

Rigol has the larger hobbyist community, primarily because the DS1054Z has been the default recommendation for years. EEVblog threads, countless YouTube tutorials, and active r/AskElectronics posts mean that virtually every Rigol question has already been answered. Siglent's community is smaller but growing and tends to attract a slightly more technical audience — engineers who prioritize specs and features over community buzz. Siglent users are often more self-sufficient with documentation. Both Rigol NA and Siglent NA provide English-language support, documentation, and firmware updates. Customer service quality is roughly equivalent in my experience. Siglent's firmware update history is generally considered more consistent — they've had fewer controversial firmware changes than Rigol.

My Honest Recommendation by Use Case

**For most hobbyists in 2026:** Buy the Rigol DHO924S ($449). The 7-inch IPS touchscreen, 250MHz bandwidth, and included protocol decoding make it the most versatile scope in its price range. Nothing from Siglent matches it at this price. **If you need CAN/LIN decoding included:** Buy the Siglent SDS1104X-U ($419). It's the most cost-effective path to automotive protocol support without paying Rigol's license fees. **If you want maximum specs at the prosumer level:** The Siglent SDS2104X Plus ($1,099) is the clear choice with its 200Mpt memory and comprehensive protocol decoding. **If you want the safest, most proven choice:** The Rigol DS1054Z at $349 has a decade of community validation, a well-documented bandwidth hack, and is still an excellent scope. The DHO924S is better, but the DS1054Z is never a wrong answer. **If budget is tight:** The Rigol DHO804 at $439 is better than anything Siglent offers for an IPS touchscreen experience at that price tier.

Frequently Asked Questions

**Is Rigol or Siglent more reliable long-term?** Both brands have good long-term reliability track records in the hobbyist community. The DS1054Z has been in the field for over a decade with very few reported hardware failures. Siglent's newer platforms have similarly solid reputations. I wouldn't choose based on reliability concerns — both are fine. **Which has better software and firmware updates?** Siglent has generally been praised for more consistent firmware updates with fewer controversial changes. Rigol's DHO series firmware has improved significantly since launch. The DS1000Z series is essentially stable at this point. **Does Siglent have better protocol decoding?** For CAN and LIN specifically, yes — it's included free while Rigol charges for it. For SPI, I2C, and UART, they're comparable. **Rigol DHO924S vs Siglent SDS1104X-U — which should I buy?** If you don't need CAN/LIN decoding: DHO924S, clearly — better display, more bandwidth, same price. If you do need CAN/LIN: SDS1104X-U saves you the license cost and delivers solid 4-channel performance. **Are Rigol and Siglent the same company?** No. They're separate Chinese companies and direct competitors, though both emerged from the same generation of Chinese test equipment manufacturers that disrupted the market in the 2000s-2010s.
