Application Programs
This chapter contains two application programs over the remote interface to
help you develop programs for your own application. Chapter 4, “Remote
Interface R eference,” startin g on
page 61, lists the syntax for the SCPI
(Standard Commands for Programmable Instruments) commands available to
program the power supply.
The examples in t his chapter have been tested on a PC running Windows
®
3.1,
Windows
®
95 or Windows
®
NT 4.0. The examples are written for use over
GPIB (IEEE 488) or RS-232. But the examples for use over the RS-232 interface
do not work with Windows 3.1. These examples require a VISA (Virtual
Instrument Software A rchitecture) driver for use with your GPIB interface
card in your PC. You should have the “
visa.dll
” for Windows
®
3.1 or
“
visa32.dll
” for Windows
®
95 or Windows
®
NT 4.0 in your
c:\windows\system
directory to have the examples in this chapter run properly . The examples step
through voltages and make corresponding current readings to characterize a
power diode.
