This chapter contains two application programs over the remote interface to help
you develop programs for your own application. Chapter 4, “Remote Interface
Reference” on page 99, 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® 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 Architecture) 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.
