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 DS1104Z-S Plus
Pros
- 100MHz bandwidth with 4 channels — no bandwidth hack needed
- Built-in 25MHz function generator saves desk space and cost
- Same excellent trigger set as the DS1054Z
- Protocol decoding (SPI, I2C, UART) included
- Proven platform for teaching labs that need scope plus signal generator
Cons
- At ~$549, the DHO924S delivers more for $100 less
- Same dated interface as the DS1054Z — no touchscreen
- No WiFi or CAN/LIN decoding at this price
- The DS1000Z platform is aging compared to the DHO series
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 DS1104Z-S Plus
The DS1104Z-S Plus is the DS1054Z with the limitations officially removed: full 100MHz bandwidth and a built-in 25MHz function generator. At ~$549, it's the premium version of a proven platform that has a decade of community support behind it. The problem in 2026 is the Rigol DHO924S — it costs $100 less, has 250MHz bandwidth, a 7-inch IPS touchscreen, WiFi, 50Mpt memory, and is generally a better scope in almost every way. The DS1104Z-S Plus's advantage is its established reliability and the integrated function generator, which the base DHO924S also includes. I'd only choose this over the DHO924S if you're buying for a teaching lab with specific software integration requirements, or if you specifically need the proven DS1000Z platform.
