Astronics / EADS / Racal 3152B Precision PLL Waveform Generator

The Astronics/EADS/Racal 3152B is a precision PLL waveform generator housed in a single-slot C-sized VXIbus module. It combines function generator and arbitrary waveform generation capabilities, delivering standard waveforms (sine, square, triangle, ramp, pulse, DC, exponential, Gaussian pulse, sinc) and user-defined arbitrary waveforms with exceptional frequency stability through phase-locked loop architecture.
