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 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
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 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.
