Overview

The ProDAQ 3951 filter/synchronization function card is a high-density card that fits into ProDAQ VXIbus motherboards and LXI function card carriers. The ProDAQ 3951 function card is a 2-channel analog filter card. It provides a set of 8-order analog filters for applications that need higher filter capabilities than those already implemented on the ProDAQ analog-to-digital converter (ADC) and digital-to-analog converter (DAC) function cards.

Each of the two analog channels contains a number of 8-order, low-pass filter stages, providing 23 different filter settings in the range of 100 Hz to 150 kHz. The built-in gain stage allows for gains of 2, 1, 0.1, and 0.01, and is suited to improve the resolution of a DAC signal filtered through this card. The synchronization circuitry allows users to generate sample clocks with a high resolution and precision for older ProDAQ function cards. The clock is synchronized to the common clock used to synchronize function cards.
