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
- At $439, the DHO924S adds 250MHz, a function gen, and double the memory for just $10 more
Rigol DS1054Z
Pros
- 4 channels at a mid-range price — still rare and genuinely valuable
- 12Mpt memory depth is excellent for long capture sessions
- Massive community: tutorials, hacks, and forum answers everywhere you look
- Well-documented bandwidth hack unlocks 100MHz — free upgrade
- Trigger types rival scopes twice the price
- Protocol decoding (SPI, I2C, UART) included at no extra cost
Cons
- 50MHz stock bandwidth is limiting for faster SPI clocks and RF work
- Interface feels dated compared to the newer Rigol DHO series
- No touchscreen — menu navigation requires physical button presses
- Fan is audible in quiet environments
- The DHO924S has overtaken it on almost every spec at a similar price
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 honest challenge at this price is the DHO924S: it costs only $10 more but gives you 250MHz bandwidth, 50Mpt memory, and a built-in function generator. At a $10 price gap, it's very hard to recommend the DHO804 over its sibling. Unless you find a significantly better deal on the DHO804 specifically, the extra $10 for the DHO924S is obviously worth it.
Rigol DS1054Z
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.
