AT-SYS-400

Overview

The AT-SYS-400 is a portable low-pass filter system designed for data acquisition systems requiring 2 to 32 channels of filtering only and simple manual adjustment of the cutoff frequency using an on-board potentiometer. The system consists of a rack-mountable chassis with space for four AAF-1 filter cards, each offering 2 to 8 channels.

Five standard filter characteristics are available for the AT-SYS-400: Butterworth, Bessel, Cauer, high-speed Cauer, elliptic, linear phase and high-speed linear phase. These filters offer variable cutoff frequencies of 0.1Hz to 200kHz, with the specific range determined by which filter type is selected.

The AT-SYS-400 chassis houses a passive backplane and high efficiency switching power supply with removable air filters to exclude dust and dirt. Designed for easy expansion, you can conveniently install and replace cards from the top of the unit. Bidirectional mounting brackets let you conveniently install the AT-SYS-400 on a wall or in a cabinet.
