Pros & Cons
Rigol DHO802
Pros
- 12-bit ADC at $329 — the cheapest way to get modern 12-bit resolution from a major brand
- Same compact form factor and touchscreen as the rest of the DHO800 series
- 25Mpt memory depth is excellent for a scope at this price
- USB-C power means you can run it from a portable battery pack
- Protocol decoding for SPI, I2C, UART, and CAN included
- Modern Rigol UI — the same intuitive touchscreen experience as the DHO924S
Cons
- Only 2 channels — the biggest limitation for embedded debugging
- 70MHz bandwidth is adequate but not exciting
- Fan noise carries over from the DHO800 series
- For ~$120 more, the DHO804 adds 2 more channels which matters enormously
- No function generator
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 DHO802
The Rigol DHO802 is the budget entry point to 12-bit oscilloscope territory, and at $329 it's genuinely compelling. You get the same modern touchscreen interface, 12-bit ADC, and compact form factor as the rest of the DHO800 series, just with 2 channels instead of 4. The 25Mpt memory and protocol decoding are both strong at this price. The honest question is whether 2 channels are enough for your work — if you're probing a single signal or doing basic Arduino debugging, absolutely. The moment you need to correlate clock and data lines on SPI, or monitor multiple signals simultaneously, you'll wish you had 4 channels. The DHO804 at ~$439 adds those extra channels, and for most users that $110 premium is worth paying upfront rather than regretting later.
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.
