Signal-conditioning module
Staff -- Test & Measurement World, 6/1/2005
Mounted on one of VXI Technology's motherboards, the VT1521 signal-conditioning module provides four channels of programmable bridge excitation with voltage values of 1 V, 2 V, 5 V, and 10 V. It also supplies wideband buffered outputs compatible with the VT1413C, VT1415A, and VT1419A series of scanning A/D converters. Independent fourth-order low-pass Butterworth filters with cutoff frequencies ranging from 100 Hz to 10 kHz protect against signal aliasing and reduce measurement noise. The VT1521 accommodates both 120-V and 350-V quarter-bridge completion resistors. VXI Technology, www.vxitech.com.
