Application Programs
This chapter contains several remote interface example programs to
help you develop programs for your own application. Chapter 4,
“Remote Interface Reference” starting on page 129, lists the syntax for
the SCPI (Standard Commands for Programmable Instruments)
commands available to program the function generator.
Introduction
Three example programs are included in this chapter and each example
illustrates the same functionality in a different programming language.
The example programs are written in BASIC for Windows
®
, Microsoft
®
Visual Basic for Windows
®
, and Microsoft
®
Visual C++ for Windows
®
.
Each example program has embedded comments to help you understand
the operation of the program. Each example covers the following topics
related to programming the function generator.
• Using the short and long form of SCPI commands.
• Configuring an AM waveform.
• Configuring an FM waveform.
• Configuring a linear frequency sweep.
• Configuring a pulse waveform with varying edge times.
• Configuring a triggered burst waveform.
• Downloading ASCII and binary data for an arbitrary waveform.
• Using the 33250A status registers.
The example programs are also included on the CD-ROM shipped with
the Agilent 33250A (see the “examples” directory). The examples are
placed in their own sub-directory based on programming language.
The “Basic” directory contains one ASCII file and you can use the BASIC
command GET “filename” to retrieve the example program. The other
two example sub-directories contain all of the project files necessary for
use with
Microsoft Visual Basic or Visual C++.
