Using Scpi Commands - Keithley DAQ6510 User Manual

Section 9: Speed scanning for increased test throughput

Using SCPI commands

This sequence of SCPI commands executes a 20-channel scan 1000 times and saves the data to the
controlling computer.
You may need to make changes so that this code will run in your programming environment. In the
table, the SCPI commands have a light gray background. The light green shaded code represents
pseudocode that will vary depending on the programming environments you use.
Send the following SCPI commands for this example application:
