Model 2601B-PULSE System SourceMeter Instrument Reference Manual Section 3: Instrument description
2601B-PULSE-901-01A April 2020 3-25
Scripts, functions, and variables that are used in the code are not saved when display.SAVE is
used. Functions and variables need to be saved with the script (see Manage scripts (on page 10-3)).
If the script is not saved in nonvolatile memory, it is lost when the 2601B-PULSE is turned off. See
Example 1 below.
Example 1:
Assume a script with a function named DUT1 has been loaded into the 2601B-PULSE, and the script
has not been saved in nonvolatile memory.
Now assume you want to add a test named Test to the USER TESTS menu. You want the test to
run the function named DUT1 and sound the beeper. The following programming example illustrates
how to add Test to the menu, define the code, and then save displayname and code in
nonvolatile memory:
display.loadmenu.add("Test", "DUT1() beeper.beep(2, 500)", display.SAVE)
When Test is run from the front-panel USER TESTS menu, the function named DUT1 executes and
the beeper beeps for two seconds.
Now assume you turn the 2601B-PULSE power off and then on again. Because the script was not
saved in nonvolatile memory, the function named DUT1 is lost. When Test is again run from the front
panel, the beeper beeps, but DUT1 will not execute because it no longer exists in the
runtime environment.
Example 2:
The following command adds an entry called Part1 to the front-panel USER TESTS submenu for the
code testpart([[Part1]], 5.0) and saves it in nonvolatile memory:
display.loadmenu.add("Part1", "testpart([[Part1]], 5.0)", display.SAVE)
Deleting USER TESTS menu entries
You can use the following function to delete an entry from the front-panel USER TESTS menu:
display.loadmenu.delete(displayname)
Where:
Name to delete from the menu.
The following programming example removes the entry named Part1 from the front-panel USER
TESTS menu:
display.loadmenu.delete("Part1")
