Application Programs
This chapter contains two application programs that utilize the remote
interface. These examples will help you develop programs for your own
application. Chapter 4 “Remote Interface Reference” starting on page 67 lists
the syntax for the SCPI (Standard Commands for Programmable Instruments)
commands available to program the power supply.
The examples in this chapter have been tested on a PC running Windows
Ò
3.1,
Windows
Ò
95 or Windows
Ò
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 Architecture) driver for use with your GPIB interface
card in your PC. You should have the “visa.dll” for Windows
Ò
3.1 or
visa32.dll” for Windows
Ò
95 or Windows
Ò
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.
