Toggling switches in the test fixture (HP 54656A only)
The user-definable output lines of HP 54656A can be used to toggle switches
in the test fixtures. The output lines of HP 54656A can be configured to
drive both level sensitive or edge sensitive switching units. A demultiplexer
or a counter IC with a demultiplexer can be used to extend the driving
capabilities of HP 54656A to more switching combinations.
For level sensitive switching units, define the corresponding output lines to
be always on or always off in a particular step to toggle the switches in the
test fixture to test the corresponding signals.
