Astronics / EADS / Racal 3155 100 MS/s PXI Arbitrary Waveform Generator

The Astronics/EADS/Racal 3155 is a 100 MS/s PXI arbitrary waveform generator delivering signal synthesis in a single-slot module. It combines function generation, arbitrary waveform synthesis, programmable sequencing, pulse generation, and modulation capabilities into one integrated instrument. The 14-bit resolution and 2 MB segmentable waveform memory support storage of up to 4096 waveforms, making it ideal for complex signal generation in aerospace, defense, and telecommunications test environments.
