Introduction to Instrument Control

Using This Chapter

Using This Chapter

This chapter is an introduction to the remote operation of your analyzer using an external
controller. The chapter is divided into two main sections:

•

“Instrument Control using the VXIplug&play Driver” on page 2-3

•

“Instrument Control using HP BASIC” on page 2-9

You should be familiar with the operation of the analyzer before attempting to remotely
control the analyzer via the General Purpose Interface Bus (GPIB). See your analyzer’s
user’s guide and reference guide for operating information.

This manual is not intended to teach programming or to discuss GPIB theory except at an
introductory level.

Programming examples that demonstrate the remote operation of the analyzer are
documented in

Chapter 7 , “Programming Examples,”

 and are also provided on the

CD-ROM that was shipped with this manual. All example programs are provided in
HP BASIC, and most are also provided in Visual C++ and Visual BASIC for use with the
VXIplug&play driver.
