This unit
The Astronics/EADS/Racal 4072 Resistance Module is a programmable dual-channel resistance module designed for precision calibration, testing, and sensor simulation in VXIbus systems. Each channel provides four decades of resistance selection with 0.01% resolution across ranges from 0.1 Ω to 1 MΩ, delivering accuracy down to ±(0.015% + 200 mΩ) on the standard 4072 model. The module supports independent or paired-channel configuration and operates within a 3 W power dissipation limit, making it suitable for high-accuracy measurement applications and digital control of potentiometric circuits.
