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.
Siglent SDS804X HD
The Siglent SDS804X HD pairs 70 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. Compare its 12-bit acquisition and 70 MHz stock bandwidth with the DHO804. Optional licenses and wireless accessories should be verified separately; they are not assumed to be included. Published acquisition limits: 2 GSa/s single-channel, 1 GSa/s dual-channel, 500 MSa/s full-channel; 50 Mpts/ch single-channel, 25 Mpts/ch dual-channel, 10 Mpts/ch full-channel. Maximum rate and depth depend on active channel configuration.
