Another way is to start with a known group of settings (for example, the factory
or user-defined power-ups) and manually change them to the configuration at
which your routine begins (this can be done within the routine, but it uses up
additional memory).
In the following example, we shall create a user-defined routine to perform
CARRIER LEVELS measurements on 10 channels at six-hour intervals. The
resultant UDP will execute a 24-hour test.
The result over 24 hours will be five sets of 10 stored results representing a set
for each time the UDP is repeated and the set stored when the UDP was first
created.
To create the user-defined routine:
1. Press [USER DEF] and select item 9, USER DEF PROG UTILITIES.
Select item 1, TITLE EDIT, and press [W] to begin editing. Enter a title of
24-HOUR LEVELS. The procedure is the same used to title a display (see
Adding Titles and Labels in this section). The title can be up to 28 characters
long. Remember to press [X] to store the title. Titling the routine is not
mandatory (if you do not supply a title, the routine is named PROGRAM #
by default) but does help you to recall what a routine is supposed to do.
2. Select item 0, ACQUIRE/EXIT KEYSTROKES, from the USER DEF
PROG UTILITIES. This begins the accumulation of keystrokes. The spectral
display reappears with the routine name superimposed and the following
message:
ACQUIRE KEY STROKES 0 BYTES
Each key that you press will now be recorded in the order in which it was
pressed. This sequence of key strokes constitutes the bulk of the user-defined
routines. The function of that key is also carried out as you watch. You can
return to the USER DEF PROGRAM UTILITIES at any time by pressing
[USER DEF].
3. Press [UTIL] [1] [1] to recall the FACTORY DEFAULT POWER-UP.
4. Select a channel table.
5. Select a channel.
6. Run a CARRIER LEVELS measurement on the selected channel.
7. Store the current CARRIER LEVELS measurement results in NVRAM.
8. Repeat steps 4 through 7 for the other nine channels.
9. Press [USER DEF] [9] [9] to select TIME DELAY SETUP.
