Message Communication
and System Functions
A
Introduction
This appendix describes the operation of instruments that operate in
compliance with the IEEE 488.2 (syntax) standard. Although the
HP 1650B and HP 1651B logic analyzers are RS-232C instruments, they
were designed to be compatible with other Hewlett-Packard IEEE 488.2
compatible instruments.
The IEEE 483.2 standard is a new standard. Instruments that are
compatible with IEEE 488.2 must also be compatible with IEEE 488.1
(HP-IB bus standard); however, IEEE 488.1 compatible instruments may
or may not conform to the IEEE 483.2 standard. The IEEE 488.2
standard defines the message exchange protocols by which the instrument
and the controller will communicate. It also defines some common
capabilities, which are found in all IEEE 488.2 instruments. This
appendix also contains a few items which are not specifically defined by
IEEE 488.2, but deal with message communication or system functions.

The syntax and protocol for RS-232C program messages and response
messages for the HP 1650B/165lB are structured very similar to those
described by 488.2. In most cases, the same structure shown in this
appendix for 488.2 will also work for RS-232C. Because of this, no
additional information has been included for RS-232C.
