This guide describes how to install and use the SCXI-1313 high-voltage
attenuator terminal block with an SCXI-1125 module.
Introduction
The SCXI-1313 high-voltage attenuator terminal block is shielded and has
screw terminals that connect to the SCXI-1125 input connector. Each
SCXI-1313 channel has a precision 100:1 resistive voltage divider that you
can use to measure voltages of up to 300 V
rms
or ±300 VDC with the
SCXI-1125. You can individually bypass these dividers for low-voltage
measurement applications.
The terminal block has 18 screw terminals for easy signal connection. One
pair of screw terminals connects to the SCXI-1125 chassis ground. When
used with the SCXI-1125, the remaining eight pairs of screw terminals
connect signals to the eight analog inputs.
