Pros & Cons
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
- In the upper-$700s, it costs more than the DHO804 while offering lower bandwidth than the DHO924S
- 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
Rigol DHO924S
Pros
- 250MHz bandwidth with 4 channels and a modern touchscreen workflow
- 7-inch IPS touchscreen with 1024x600 resolution — sharp and responsive
- 50Mpt memory depth for extended captures
- Built-in function generator and WiFi connectivity included
- Modern phone-like interface has almost no learning curve
- Protocol decoding for SPI, I2C, UART, CAN, and LIN
Cons
- 1.25GSa/s sample rate could be higher given the 250MHz bandwidth
- Newer platform means less community documentation than the DS1054Z
- Some early firmware bugs have been reported — check version before updating
- Fan can be audible in a quiet room
Our Verdicts
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 that pure oscilloscope buyers can either spend less on a DHO804 or spend more on the 250MHz DHO924S. The DHO914S only pulls ahead if you need the logic analyzer capability or the Bode plot feature for control loop design.
Rigol DHO924S
The Rigol DHO924S is no longer the default hobbyist oscilloscope recommendation now that Amazon pricing is around $899. The 7-inch IPS touchscreen is still excellent — pinch to zoom, tap to place cursors, swipe to scroll through captures — and the spec stack is serious: 250MHz bandwidth, 4 channels, 50Mpt memory, a function generator, WiFi, and CAN/LIN protocol decoding. But at this price it belongs in the premium-upgrade tier, not the beginner tier. Buy it if you need the bandwidth, mixed-signal-ready feature set, and modern Rigol workflow. Most first-time buyers should start with the DS1054Z or DHO804 instead.
