The V375 is a versatile VME four-channel arbitrary waveform generator. The module architecture was designed in cooperation with major aircraft engine and power systems manufacturers to provide the features needed for accurate simulation of real-world sensor inputs.
The module is ideal for:The V375 builds on the success of its predecessor, the V370, by extending the output bandwidth to 300 kHz and adding four inputs for user waveforms to sum into the channel outputs. A new burst mode allows software or external input to trigger generation of one or more waveform cycles.
