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 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 ~$699, it is no longer the obvious value play next to newer touchscreen scopes
- 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 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 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 ~$699, it's the premium version of a proven platform that has a decade of community support behind it. The problem in 2026 is that newer touchscreen scopes have made the DS1000Z platform feel dated. The DHO924S costs more now, but it brings 250MHz bandwidth, a 7-inch IPS touchscreen, WiFi, 50Mpt memory, and a much more modern workflow. I'd only choose the DS1104Z-S Plus if you're buying for a teaching lab with specific software integration requirements, or if you specifically need the proven DS1000Z platform.
