Pros & Cons
Rigol DHO804
Pros
- 7-inch IPS touchscreen — same display as the DHO924S
- 25Mpt memory depth is solid for extended capture sessions
- Modern, intuitive interface makes learning easy
- 4 channels with protocol decoding (SPI, I2C, UART)
- WiFi connectivity for remote viewing and data export
Cons
- 70MHz bandwidth is the real compromise — limits this scope's ceiling
- No built-in function generator unlike the DHO924S
- 25Mpts memory is half the DHO924S's 50Mpts
- Stepping up to the DHO924S now costs substantially more
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
Our Verdicts
Rigol DHO804
The Rigol DHO804 is the entry point to Rigol's DHO platform, offering the same 7-inch IPS touchscreen experience as the DHO924S with 70MHz bandwidth and 25Mpt memory at $439. For Arduino, basic analog work, and learning, 70MHz is genuinely sufficient — most signals you'll encounter stay well under this limit. The old objection was that the DHO924S cost almost the same; that is no longer true. With the DHO924S now priced like a premium scope, the DHO804 is the modern Rigol touchscreen pick for buyers who want a current interface without jumping near $900.
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.
