Application Programs
This chapter contains several remote interface application programs to help
you develop programs for your own application. Chapter 4, “Remote
Interface Reference,” starting on page 63, lists the syntax for the SCPI
(Standard Commands for Programmable Instruments) commands available
to program the power supply.
Agilent BASIC Programs
All of the Agilent BASIC example programs in this chapter were developed and
tested on an HP 9000 Series 300 controller. Each device on the GPIB
(IEEE-488) interface must have a unique address. You can set the power
supply's address to any value between 0 and 30. The current address is
displayed momentarily on the front panel when you turn on the power supply.
The GPIB (IEEE-488) address is set to “05” when the power supply is
shipped from the factory. The example programs in this chapter assume an
GPIB address of 05. When sending a command over the remote interface,
you append this address to the GPIB interface's select code (normally “7”). For
example, if the select code is “7” and the device address is “05”, the combination
is “705”.
C and QuickBASIC Language Programs
All of the C and QuickBASIC Language example programs in this chapter are
written for the Agilent 82335 GPIB Interface Card using the GPIB Command
Library for C. Unless otherwise noted, the library functions used in the
example programs are compatible with the ANSI C standard.
All of the C Language programs were compiled and tested using the
following compilers:
• Microsoft
Ò
QuickC
Ò
Version 2.0
• Borland
Ò
Turbo C
Ò
++ Version 1.0
To compile the program to make an executable file, refer to the language
manuals. To link the object file you must previously specify TCLHPIB.LIB as
a required library file from the menu.
