HP / Agilent 54201A 300 MHz DIGITIZING OSCILLOSCOPE

The HP/Agilent 54201A is a two-channel digital storage oscilloscope delivering simultaneous real-time and repetitive waveform acquisition for electronic testing and measurement. It combines a 300 MHz repetitive bandwidth with 50 MHz single-shot bandwidth and a maximum sample rate of 200 megasamples/second, enabling capture of both fast transients and repetitive signals across diverse applications.
