Tektronix VX4792

The Tektronix VX4792 is a VXIbus Arbitrary Waveform Generator that delivers custom signal generation for complex test environments. Operating at 250 MHz bandwidth with a 250 MS/s sample rate and 12-bit amplitude resolution, the VX4792 generates intricate waveforms from a 256 K word memory bank. Its two independently programmable marker channels synchronize with waveform data points at 4 ns/point resolution, enabling precise signal control.
