You may need to make changes so that this code will run in your programming environment.
Send the following commands for this example application:
Command Description
*RST
TRIG:LOAD:LOOP:SIMP 100
SENS:FUNC "RES"
SENS:RES:RANG:AUTO ON
SENS:RES:OCOM ON
SENS:RES:RSEN ON
DISP:SCR PLOT
OUTP ON
INIT
*WAI
TRAC:DATA? 1, 100, "defbuffer1", READ, REL
OUTP OFF
•
Reset the Model 2460.
• Configure Simple Loop trigger model
template to make 100 readings.
• Set to measure resistance.
• Turn on auto range.
• Enable offset compensation.
• Set to use 4-wire sense mode.
• Show the TREND swipe screen.
• Turn on the output.
• Initiate readings.
• Wait until finished.
• Read the resistance and time values from
defbuffer1.
• Turn off the output.
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
2460 Reference Manual.
To use other programming environments, you may need to make changes to the example TSP code.
By default, the Model 2460 is configured to use 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 display the TREND
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.
