Determine the command set to use
You can control the 2450 with command sets that are based on the SCPI or Test Script Processor
(TSP
®
) programming languages. You can change the command set that you use with the 2450. The
remote command sets that are available include:
• SCPI: An instrument-specific language built on the SCPI standard.
• TSP: A scripting programming language that contains instrument-specific control commands that
can be executed from a stand-alone instrument. You can use TSP to send individual commands
or use it to combine commands into scripts.
• SCPI 2400: An instrument-specific language that allows you to run code developed for earlier
Series 2400 instruments.
If you change the command set, reboot the instrument.
You cannot combine the command sets.
As delivered from Keithley Instruments, the 2450 is set to work with the SCPI command set.
If you choose the SCPI 2400 command set, you will not have access to some of the extended
ranges and other features that are now available using the SCPI command set. In addition, some
Series 2400 code will work differently in the 2450 than it did in the earlier instrument. See “2450 in a
Model 2400 application” in the Model 2450 Reference Manual for information about the differences.
To set the command set from the front panel:
1. Press the MENU key.
2. Under System, select Settings.
3. Select the appropriate Command Set.
You are prompted to confirm the change to the command set and reboot.
