Agilent / Keysight DSOS804A High-Definition Oscilloscope: 8 GHz, 4 Analog Channels

The Agilent/Keysight DSOS804A is an 8 GHz, 4-analog channel high-definition oscilloscope engineered for signal integrity analysis and demanding measurement tasks. This instrument combines a 10-bit ADC with high-resolution mode capability reaching 16 bits of vertical resolution, delivering superior measurement detail across extended signal captures. Maximum sample rates reach 20 GSa/s on 2 channels and 10 GSa/s across all 4 channels, with standard memory depth of 100 Mpts per channel expandable to 800 Mpts.

The system achieves an average ENOB of 8.1 bits at full bandwidth and an ADC ENOB up to 8.7 bits, ensuring high-fidelity signal acquisition.
