Pros & Cons
Rigol DHO814
Pros
- 4 analog channels for simultaneous signal comparison
- 100 MHz nominal bandwidth; 25 Mpts acquisition memory
- Protocol decoding: SPI, I2C, UART, CAN
Cons
- 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.

Our Verdicts
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.
Rigol DHO924S
The Rigol DHO924S pairs 250 MHz nominal bandwidth with 4 analog channels and 50 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. Its 250 MHz nominal bandwidth and included generator make it worth comparing when a 70 MHz entry-level scope would constrain the work. Verify optional digital-channel accessories separately. Published acquisition limits: 1.25 GSa/s single-channel, 625 MSa/s dual-channel, 312.5 MSa/s full-channel; 50 Mpts single-channel, 25 Mpts dual-channel, 10 Mpts full-channel. Maximum rate and depth depend on active channel configuration.
