Writing Programs

Controlling the Analyzer

Instrument BASIC can control the analyzer (itself) through the \internal" GPIB bus. This means
that an analyzer with Instrument BASIC includes both a controller and an analyzer in the same
instrument. They are connected through an internal GPIB bus.
The select code of the internal GPIB interface is 8, and the GPIB address of the
Note
analyzer can be any number from 0 to 30. In this manual, we use \800" for the
device selector of the analyzer.
For more information on GPIB addresses and device selectors, see \Device
Selectors" in the
BASIC Users Handbook
Chapter 9.
You can write the program by using the keyboard or by pressing keys and softkeys from the
front panel procedure without using the external keyboard. Using the keyboard is very useful
when you write a larger and more complex program, or type comments in a program. For
detailed information on how to use the keyboard, see Appendix C.
