Programming Examples
The following series of commands and queries illustrate many of the most
common commands and techniques.
To use these commands and queries over USB, you must use a program or
routines that interface to the USBTMC driver on your PC. You can also use the
PC Communications software that came on the CD with your instrument to get
the same data without having to write programs. For operating information, you
can launch the PC Communications software and refer to the online help.
To use these commands and queries over GPIB, you must use a program or
routines that interface to the GPIB hardware in your computer. The software is
usually supplied by the GPIB hardware manufacturer.
