The Astronics/EADS/Racal 6062B4 is a 4-channel analog output module engineered for precision signal generation in automated testing, industrial control, and waveform synthesis applications. This C-size VXIbus module delivers 16-bit resolution across four independent channels with ±10 V output range and ±50 mA sourcing/sinking capability per channel. It combines deterministic settling performance with flexible triggering architecture, supporting both SCPI messaging and pseudo-register control for microsecond-level response times.
