Astronics / EADS / Racal 6062A 4-Channel Analog Input / 4-Channel Analog Output Module

The Astronics/EADS/Racal 6062A is a VXI plug-and-play module combining 4-channel analog input and 4-channel analog output in a single card. It integrates digitizer and waveform generator functionality for high-performance data acquisition and real-time signal generation in test systems. The module supports flexible memory configurations up to 576 k-points, independent or synchronized triggering across channel groups, and dual control modes—SCPI messaging or pseudo-register programming for optimized throughput.
