Pros & Cons
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
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 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.
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.
