Model 2651A High Power System SourceMeter® Instrument Reference Manual Section 6: Instrument programming

For example, to set up a two-second beep, you could 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.script table entries are made

to the runtime environment as shown in the following figure.

Create an unnamed script using script.new()

NOTE

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

runtime 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, if you sent the command:

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

A script is created in the runtime environment and a global variable is created that references the

script.

To run the script, send the command:

hello()
