Pros & Cons
Rigol DS1054Z
Pros
- 4 channels for $349 — nearly every competitor at this price is 2-channel, making it the go-to pick when you need clock, data, enable, and ground all visible at once
- 12Mpt memory depth captures long protocol bursts that 1–2Mpt scopes miss — a full UART session at 115200 baud across hundreds of milliseconds stays in buffer without retriggering
- A well-documented firmware procedure unlocks 100MHz bandwidth from the stock 50MHz — the community has published step-by-step guides since 2015 and it takes under 10 minutes
- SPI, I2C, UART, and RS232 protocol decoding included with no upsell — some competitors charge extra license fees for the same decoders
- Ten years of community answers: searching 'DS1054Z + [your problem]' returns solved threads on EEVblog, r/AskElectronics, and YouTube before you finish typing
Cons
- 50MHz stock bandwidth can't cleanly capture SPI clocks above ~10MHz or RF signals — the firmware unlock helps, but it's still a soft ceiling
- Menu navigation is physical-button-only — no touchscreen, no scroll wheel; takes a few sessions to get fluent
- Interface looks dated next to modern touchscreen scopes; not a functional problem, but noticeable
- Anyone doing daily professional bench work should budget for the DHO924S — the touchscreen and 250MHz bandwidth are genuinely worth the extra $550 at that usage level
Siglent SDS1202X-E
Pros
- 200MHz bandwidth — 4x the stock DS1054Z at nearly the same price
- 14Mpt memory depth is excellent for capturing long waveforms
- Protocol decoding includes CAN and LIN — Rigol charges extra for these
- SPL (Siglent Programming Language) for scripting and automation
- Serial decode is free, not locked behind a paid license
Cons
- Only 2 channels — the fundamental tradeoff versus the DS1054Z
- Interface is less intuitive than Rigol's — steeper learning curve
- Smaller community means fewer tutorials and answered questions online
- No touchscreen — button-heavy navigation
- No function generator
Our Verdicts
Rigol DS1054Z
If you're buying your first oscilloscope to learn embedded systems, debug Arduino or ESP32 projects, or study signals at school, buy the DS1054Z — 4 channels, full protocol decoders, and a decade of community support for $349 is a package that still has no real competition at this price. Don't buy it if you do professional bench work daily or need clean capture above 50MHz; for that, the DHO924S at $899 is the right tool. The honest tradeoff: DS1054Z gives you 4 channels and the largest hobbyist knowledge base on the internet; DHO924S gives you 250MHz and a touchscreen for $550 more. For a first scope for a hobbyist, student, or maker, this is the buy.
Siglent SDS1202X-E
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.
