Instrumentation) instruments: GPIB, VXI, and GPIB- VXI.

This chapter provides information to program GPIB and VXI

devices via the GPIB, VXI or GPIB- VXI interfaces, including:

• GPIB and VXI Interfaces Overview

• Using High- Level Memory Functions

• Using Low- Level Memory Functions

• Using High/Low- Level Memory I/O Methods

• Using the Memory Access Resource

See Chapter 3, “Programming with VISA”, for general

information on VISA programming for the GPIB, VXI, and

GPIB- VXI interfaces. See the VISA Online Help for
