Using SCPI commands
You may need to make changes so that this code will run in your programming environment.
Send the following commands:

▪
Reset the DMM7510.
▪
Set the instrument to measure digitize
voltage.
▪
Set range to 10 V.
▪
Set the input impedance to automatic, which
selects 10
GΩ for the 10 V range.
▪
Set the sample rate to 1,000,000.
▪
Enable automatic aperture.
▪
Set the sample count to 1 (optional).
▪
Set
defbuffer1
to store 10,000 points.
▪
Clear
defbuffer1
.
▪
Enable analog edge trigger.
▪
Set the edge trigger to rising slope.
▪
Set the edge trigger level to 3 V.
▪
Set up a trigger model that digitizes voltage
indefinitely while waiting for the edge trigger
event and digitizes 50% post trigger readings.
▪
Start the trigger model.
▪
Wait for the trigger model to complete.
▪
Retrieve the readings from the buffer.
▪
Retrieve the relative timestamps from
the buffer.
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 tek.com/keithley . 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 DMM7510 uses the SCPI command set. You must select the TSP command set
before sending TSP commands to the instrument.
