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 DHO814
Pros
- 12-bit ADC — the Reddit community now considers this mandatory for new scope purchases
- Compact form factor is noticeably smaller and lighter than the DHO900 series
- Same modern touchscreen interface as the DHO924S — intuitive and responsive
- 100MHz bandwidth handles most hobbyist and embedded signals comfortably
- USB-C power input means you can run it from a power bank in the field
- CAN decoding included — Rigol doesn't always include this on lower-tier models
Cons
- Fan noise is a known complaint in the DHO800 series — audible in quiet rooms
- At ~$549, you're only $10 below the DHO924S which has 250MHz bandwidth
- 25Mpt memory is half the DHO924S's 50Mpts
- No built-in function generator
- The Siglent SDS804X HD offers similar 12-bit performance for $100 less at 70MHz
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 DHO814
The Rigol DHO814 is the mid-tier entry in Rigol's 12-bit DHO800 lineup, offering 100MHz bandwidth and 4 channels in a compact, USB-C-powered package. The 12-bit ADC is the real story here — the Reddit community has essentially made 12-bit resolution the new baseline for oscilloscope recommendations, and the DHO814 delivers. The compact form factor and power bank compatibility are genuine advantages over the larger DHO900 series. The uncomfortable truth is pricing: at ~$549, you're within striking distance of the DHO924S at $449 which gives you 250MHz bandwidth and 50Mpt memory. The DHO814 only makes sense if you specifically value the smaller size or find it on sale significantly below MSRP.
