Synchronizing the
Multimeter With a
Switch Module
This program example demonstrates how to synchronize the multimeter
with a switch module. The 4152A uses the TTL triggers from the VXI
backplane to trigger the multimeter and advance the channel scan list. The
example uses the Racal 1260-38 128-Channel Multiplexer Module but will
also work with any Racal Multiplexer module as long as the scan list is
specified properly. Figure 2-2 illustrates the set up. The switch module
(multiplexer) and multimeter use the VXI backplane to communicate the
trigger and VM Complete signals to each other to synchronize the scan.
