Types of Examples

This section includes examples of how to program the instrument using the instrument SCPI programming commands. Most of the examples are written for a PC, using GPIB. They are written in C using the Agilent VISA transition library. The VISA transition library must be installed and the GPIB card configured. The Agilent I/O libraries contain the latest VISA transition library and is available at: www.agilent.com/iolib.

These examples are available on the Agilent Technologies E4406A documentation CD-ROM. They are also available at the URL

The section “C Programming Using VTL” on page 113, includes some basic information about using the C programming language. That information can be used with the examples in this chapter to create your own measurement routines.

Examples are also available showing you how to program the instrument using the VXI plug&play instrument driver that is provided. Examples are included in the on-line documentation in the driver itself. The driver allows you to use several different programming languages including: VEE, LabView, C, C++, and BASIC. The software driver can be found at the URL http://www.agilent.com/find/vsa.
