VBAT-PB Operation

When the VBAT is properly installed and detected by the-VBT-325 (or VPC),
the Setup screen will include the command ' vbat ' in the main command bar,
see figure below.

VBAT-to-VBT trigger signal

In addition to trigger output signals that can be used to trigger other external
instruments (see later in this manual), the VBAT-PB also generates a trigger

signal that is automatically fed to a dedicated input channel in the VME part of
the VBT-325. As such, this signal can be part of the VBT-325 trigger, and the
trigger signal is also visible in the trace.

If the VBAT is going to be used interactively together with the VBT-325 (e.g.
to identify which cycles caused a VMEbus violation), it is a good idea to insert
the VBAT trigger signal to the Vl3T-325 in the Event Patterns window at this
point. This is easily done by executing the command
