Section 6: Instrument programming Model 2657A High Power System SourceMeter® Instrument Reference Manual

For example, to set up a two-second beep, you can send the command:

beepTwoSec = script.new("beeper.enable = 1 beeper.beep(2, 2400)", "beepTwoSec")

To run the new script, send the command:

beepTwoSec()

When you add beepTwoSec, the global variable and script.user.scripts table entries are

made to the run-time environment as shown in the following figure.

Figure 96: Runtime environment after creating a script

Create an unnamed script using script.new()

Unnamed scripts are not available from the front-panel display of the instrument. Only the anonymous

script and named scripts are available from the front-panel display.

When you create a script using script.new(), if you do not include name, the script is added to the

run-time environment as an unnamed script. The script.new() function returns the script. You can

assign it to a global variable, a local variable, or ignore the return value. A global variable is not

automatically created.

For example, send the following command:

hello = script.new('display.clear() display.settext("hello")')

A script is created in the run-time environment and a global variable is created that references the

script.

To run the script, send the command:

hello()
