HP WaterSkis E1412A, WaterSkis E1312A manual Synchronizing Multimeter With a Switch Module

Synchronizing the

Multimeter With a

Switch Module

This program example demonstrates how to synchronize the multimeter with a switch module. For the HP E1412A it uses the TTL triggers from the VXI backplane to trigger the multimeter and advance the channel scan list. The example uses the HP E1476A 64-Channel Multiplexer Module but will also work with any HP switch module as long as the channel list is specified properly. Figure 2-2 illustrates the C-size 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.

Figure 2-3 shows the HP E1312A set up using external triggering. B-size command modules do not support VXIbus TTL triggers.
