7-8 Programming Examples
These are more comprehensive program listings which provide further
examples of multiple commands involving program loops and sub
routines
This program shows how to program and change some of the
HP 8112A parameters periodically. In this example every 2 second
Delay will be incremented by 1 ms while Width is decremented by 2
ms.
The interface is initialized and the HP 8112A is set to the standard
settings (see Chapter)
Lines 100 to 120 setup period, delay, width, high-level, and low-level
and line 130 enables the output.
The test signal is now output from the HP 8112A.
In the "Width and delay loop" (lines 250 to 350), every 2 second
delay is incremented by 1 ms while width is decremented by 2 ms.
The current values are printed in the Display subroutine (lines 440 to
490).
Width finally reaches the value of 2 ms.
The output is not automatically disabled when the program is exited.
