The Sequencing Menu
Pressing the key accesses the Sequencing menu. This menu leads to a series of menus that

Sequence Command
The located in the Sequencing menu, activates a feature that allows
::
the sequence to branch off to another sequence, then return to the original sequence. For
example, you could perform an amplifier measurement in the following manner:
1. Create sequence 1 for the specific purpose of performing the gain measurement and printing
the results. This sequence will act as a sub-routine.
2. Create sequence 2 to set up a series of different input power levels for the gain
measurements In-between each power level setting, call sequence 1 as a sub-routine by

the individual output bits Refer to Figure 6-81 for output bus pin locations.
Input Decision Making
Five compatible input lines can be used for decision making in test sequencing. For
example, if a test is connected to the port and has a micro switch that needs to
be activated in order to proceed with a measurement, you can construct your test sequence
so that it checks the state of the input line corresponding to the switch. Depending on
whether the line is high or low,
you
can jump to another sequence. access these decision
