FAQs
My data looks odd or is wrong. What should I do?
Verify the connections from the instrument to the test fixture. Also
check the connections from the DUT to the test fixture socket.
How do I change the command set?
In addition to the front-panel options, you can use a remote interface
to set up the instrument. You can choose one of the following
command sets:
 SCPI: An instrument-specific language built on the SCPI
standard.
 TSP: A programming language that you can use to send
individual commands or combine commands into scripts.
You cannot combine the command sets.
As delivered from Keithley Instruments, the Model 2461 is set to
work with the SCPI command set.
To set the command set using the front panel:
1. Press the MENU key.
2. Under System, select Settings.
3. Select the button next to Command Set.
4. Select the command set.
5. You are prompted to reboot.
