Agilent/Keysight EXR104A

The Keysight EXR104A is a 1 GHz real-time oscilloscope built for R&D, manufacturing test, and advanced education. Four analog channels deliver 16 GSa/s sampling with 100 Mpts standard memory per channel, expandable to 1.6 Gpts combined flexible memory. A 10-bit ADC with high-resolution mode up to 16-bit ensures measurement fidelity down to 43 µV noise floor, while waveform update rates exceed 200,000 wfm/s and eye diagram acquisition speeds reach 750,000 UI/s.
