Using SCPI commands
You may need to make changes so that this code will run in your programming environment.
Send the following commands:
Command Description
:SENS:DIG:FUNC "VOLT"
:SENS:DIG:VOLT:RANG 10
:SENS:DIG:VOLT:INP AUTO
:SENS:DIG:VOLT:SRATE 1000000
:SENS:DIG:VOLT:APER AUTO
:SENS:DIG:COUN 100
:TRAC:POIN 100
:TRAC:CLE
:TRAC:TRIG:DIG
:TRAC:DATA? 1, 100, "defbuffer1", READ
:TRAC:DATA? 1, 100, "defbuffer1", REL
•
• Set the instrument to measure digitize voltage.
• Set range to 10 V.
• Set the input impedance to 10 GΩ.
• Set the sample rate to 1e6.
• Enable automatic aperture.
• Set the sample count to 100.
• Set defbuffer1 to store 100 points.
• Clear defbuffer1.
• Digitize the signal.
• Read the first 100 measurement and relative
timestamp values from defbuffer1.
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
DMM7510 Reference Manual.
To use other programming environments, you may need to make changes to the example TSP code.
By default, the Model DMM7510 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.
