Line Description
1 This line is required to use the VISA COM library.
5 to 23 Main subprogram establishes the software connection with the Keysight E5260/E5270,
resets the E5260/E5270, opens a message box to confirm the start of measurement, and
pauses program execution until OK is clicked on the message box. By clicking OK, the
program displays a message on the console window, enables the SMUs, and calls the
perform_meas subprogram that will be used to perform measurement.
After the measurement, the program disables all SMUs, disables the software connection
with the E5260/E5270, and opens a message box to confirm the end of the program. Finally,
by clicking OK on the message box, the program displays a message on the console window.
9 The above example is for the E5260/E5270 of the GPIB address 17 on the interface GPIB0.
“GPIB0” is the VISA name. Confirm your GPIB settings, and set them properly.
14 to 15 The above example uses the SMUs installed in the E5260/E5270 slots 1, 3, 4, and 5. Change
the slot numbers for matching your configuration.
