Using the SCXI-1127/1128
This chapter discusses in detail the operation of the SCXI-1127/1128.
There are two major modes of operation: multiplexer and matrix. A third
mode of operation, independent mode, allows you to access advanced
features of the SCXI-1127/1128.
Operating as a Multiplexer/Scanner
You can configure the SCXI-1127/1128 to operate as a
multiplexer/scanner. Using this mode of operation, you can configure
channels in the scan in three different ways: 2-wire, 1-wire, and/or 4-wire
channel configurations. In all scanning modes, only one channel is closed
at a time in the multiplexer.
