Agilent/Keysight DSO80804B

The Agilent/Keysight DSO80804B is an 8 GHz Infiniium series oscilloscope engineered for high-fidelity signal acquisition and analysis in telecommunications, semiconductor testing, and advanced R&D environments. This four-channel instrument delivers up to 40 GSa/s sampling across two channels and captures waveforms with exceptional signal integrity through noise floor, jitter floor, and trigger jitter specifications.
