Set up the low-resistance application using TSP commands
The following TSP code is designed to be run from Keithley Instruments Test Script Builder (TSB).
TSB is a software tool that is available from the Keithley Instruments website. You can install and
use TSB to write code and develop scripts for TSP-enabled instruments. Information about how to
use TSB is in the online help for TSB and in the “Introduction to TSP operation” section of the Model
2461 Reference Manual.
To use other programming environments, you may need to make changes to the example TSP code.
By default, the Model 2461 uses the SCPI command set. You must select the TSP command set
before sending TSP commands to the instrument.
To enable TSP commands:
1. Press the MENU key.
2. Under System, select Settings.
3. For Command Set, select TSP.
4. At the prompt to reboot, select Yes.
This sequence of TSP commands makes 100 low-resistance measurements by sourcing current and
measuring resistance. In this example, the source current magnitude and limit voltage are set
automatically. It uses remote commands to change the front-panel display to show the GRAPH swipe
screen. This allows you to view numeric data at the top of the screen and graphic data at the bottom
of the screen. After the code executes, the data is displayed in the Instrument Console of Test Script
Builder.
