Setting up the low-resistance test using TSP commands
The following example TSP code is designed to be run from Keithley Instruments Test Script Builder
(TSB). TSB is a software tool included on one of the CD-ROMs that came with your Model 2450.
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 2450 Reference Manual.
To use other programming environments, you may need to make changes to the example TSP code.
By default, the Model 2450 is configured to use SCPI commands. You must select the TSP command
set before attempting to send TSP commands to the instrument.
To enable TSP commands:
1. Press the
MENU
key.
2. Under System, select
Settings
.
3. Select the button next to Command Set and select
TSP
.
4. You are prompted to reboot. Select
Yes
.
In this example, the Model 2450 is configured to take 100 low-resistance readings by sourcing current
and measuring resistance. The front-panel display is changed using remote commands to show the
DATA TREND swipe screen. This allows you to view the data numerically at the top of the screen and
graphically at the bottom of the screen. After the code is executed, the data appears in the Instrument
Console of Test Script Builder.
