Introduction
This chapter describes the SCXI-1104/C modules, lists what you need to
get started, and explains how to unpack the module. A table at the end of
this chapter lists vendors who manufacture mating connectors for
developing custom cables.
About the SCXI-1104/C Module
The SCXI-1104/C modules are for signal conditioning medium-voltage
signals. The SCXI-1104/C has 32 differential analog input channels. Each
channel also has a divide-by-10 attenuator stage before the amplifier. You
can multiplex the SCXI-1104/C inputs to a single module output that drives
a DAQ device input channel.
♦
SCXI-1104
On each channel, the SCXI-1104 has a three-pole lowpass filter with a
2 Hz cutoff frequency to reject 60 Hz noise.
♦
SCXI-1104C
On each channel, the SCXI-1104C has a three-pole lowpass filter with a
10 kHz cutoff frequency.
Detailed specifications of the SCXI-1104/C modules are in Appendix A,
. Figure 5-1,
