Pros & Cons
Rigol DHO802
Pros
- 2 analog channels for simultaneous signal comparison
- 70 MHz nominal bandwidth; 25 Mpts acquisition memory
- Protocol decoding: SPI, I2C, UART, CAN
Cons
- 1.25 GSa/s single-channel, 625 MSa/s full-channel; 25 Mpts single-channel, 10 Mpts full-channel. Maximum rate and depth depend on active channel configuration.
- Two analog channels limit simultaneous bus and power-rail captures
- Specification-based assessment; no hands-on measurement record is documented
Rigol DHO814
Pros

Our Verdicts
Rigol DHO802
The Rigol DHO802 pairs 70 MHz nominal bandwidth with 2 analog channels and 25 Mpts acquisition memory. Its two channels suit input/output or clock/data comparisons, but leave less room for simultaneous power-rail debugging. Protocol decoding can help interpret supported serial buses; check the exact included decoder options. Choose capture duration and sample rate together; maximum memory and sample rate may depend on the enabled channel count. This recommendation is based on listed specifications, without documented hands-on performance testing. Published acquisition limits: 1.25 GSa/s single-channel, 625 MSa/s full-channel; 25 Mpts single-channel, 10 Mpts full-channel. Maximum rate and depth depend on active channel configuration.
Rigol DHO814
The Rigol DHO814 pairs 100 MHz nominal bandwidth with 4 analog channels and 25 Mpts acquisition memory. Four analog channels let you compare multiple rails or related signals in one capture. Protocol decoding can help interpret supported serial buses; check the exact included decoder options. Choose capture duration and sample rate together; maximum memory and sample rate may depend on the enabled channel count. This recommendation is based on listed specifications, without documented hands-on performance testing. Published acquisition limits: 1.25 GSa/s single-channel, 625 MSa/s dual-channel, 312.5 MSa/s full-channel; 25 Mpts single-channel, 10 Mpts dual-channel, 5 Mpts full-channel. Maximum rate and depth depend on active channel configuration.
