5-1. Introduction

The 5790A AC Measurement Standard operates in local mode from the front panel
controls or under remote control of an instrument controller, computer, or terminal.
Remote control can be interactive, with the user controlling each step from a terminal, or
under the control of a computer program running the 5790A in an automated system.
This section tells you how to connect, configure, and operate the 5790A in remote mode.
Section 6 is a command reference that describes all alphabetized commands in detail.
You can control the 5790A using a computer or terminal connected to the RS-232 serial
port, or an IEEE-488 instrument controller connected to the IEEE-488 interface
connector. When you control the 5790A through the serial port, you can set the 5790A to
respond to queries in a conversational style for interactive control purposes, or to respond
to queries in an abbreviated style for interpretation by a computer program. The
following information tells how to set up for remote control, first for IEEE-488 (GPIB)
controller use, then for remote control through the RS-232-C serial interface.

5-2. Using the IEEE-488 Interface for Remote Control

The 5790A is fully programmable for use on the IEEE Standard 488.1 interface bus
(IEEE-488 bus). The interface is also designed in compliance with supplemental standard
IEEE-488.2. Devices connected to the bus in a system are designated as talkers, listeners,
talker/listeners, or controllers. Under the remote control of an instrument controller such
as the Fluke 1722A, the 5790A operates exclusively as a talker/listener on the IEEE-488
bus.
This manual assumes you know the basics of the IEEE-488 interface bus. For an
introduction to the bus, request Fluke Application Bulletin AB-36, <italic>IEEE Standard
488-1978 Digital Interface for Programmable Instrumentation.

IEEE-488 Bus Restrictions

The following restrictions apply to all IEEE-488 systems:
1. A maximum of 15 devices can be connected in a single IEEE-488 bus system.
2. The maximum length of IEEE-488 cable used in one IEEE-488 system is the lesser of
either 20 meters or 2 meters times the number of devices in the system.

IEEE-488 Bus Setup Procedure

Setting up the 5790A on the IEEE-488 bus requires only a choice of address and
connection to a controller. To set up the 5790A for remote operation,proceed as follows:
Press [UTIL MENUS] followed by the "Setup" softkey. The instrument setup menu
appears:
