Overview

The ProDAQ 3201 voltage reference card is available for ProDAQ VXIbus motherboards and LXI function card carriers. Two signal lines are available to distribute the reference voltage to the ProDAQ function cards. This allows the distribution as a differential signal to overcome possible noise pick-up. It is possible to distribute two voltages to the function cards, providing an additional system advantage. The attenuator is programmable from 1 to 1000, providing the user with calibration points from ±4.5 V to ±4.5 mV with RMS noise less than 1 µV.

The ProDAQ 3201 programmable voltage reference card can be switched directly to the programmable gain amplifier of different ProDAQ analog-to-digital converter (ADC) function cards for on-the-fly calibration or self-test purposes.
