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 DHO914S
Pros
- Built-in 25MHz arbitrary waveform generator — saves buying a separate signal source
- 16 digital channels available via optional logic probe — true mixed-signal capability
- 12-bit ADC with 125MHz bandwidth is a solid all-around combination
- 50Mpt memory depth matches the DHO924S
- Same compact DHO form factor with USB-C power support
- Bode plot analysis built in — useful for filter and feedback loop characterization
Cons
- At ~$549, you're paying $100 more than the DHO924S which has 250MHz bandwidth
- 125MHz bandwidth is lower than the DHO924S's 250MHz
- Logic analyzer probe is an additional purchase — not included
- Fan noise is present, consistent with the DHO series
- The DHO924S also includes a function generator, making the price gap harder to justify
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 DHO914S
The Rigol DHO914S is Rigol's Swiss Army knife oscilloscope — 4 analog channels, a 25MHz function generator, optional 16-channel logic analyzer, and Bode plot analysis in the compact DHO form factor. The mixed-signal capability is the real differentiator: if you're debugging embedded systems where you need to correlate analog and digital signals simultaneously, the logic analyzer option makes this genuinely useful in ways a pure analog scope isn't. The built-in AWG saves you $100-200 on a standalone function generator. The catch is the DHO924S at $449 — it also has a function generator and offers 250MHz bandwidth for $100 less. The DHO914S only pulls ahead if you need the logic analyzer capability or the Bode plot feature for control loop design. For pure oscilloscope work, the DHO924S remains the better value.
