Agilent DSO80804A 8 GHz Sigital Signal Oscilloscope

The Agilent DSO80804A is an 8 GHz digital signal oscilloscope with 4 analog channels designed for high-speed signal acquisition and waveform analysis. It delivers real-time sample rates up to 40 GSa/s on two channels and 20 GSa/s across four channels, capturing fast transients and periodic signals with minimal aliasing. The instrument combines jitter performance - trigger jitter below 500 fs RMS and measurement floor below 500 fs - with the lowest vertical noise floor (less than 419 μV @ 5 mV/div, 13 GHz) for accurate characterization of RF and high-speed digital signals.

Upgradeable to 13 GHz bandwidth, the DSO80804A supports demanding R&D applications in high-speed electronics.
