Introduction

This chapter describes the operation of instruments that operate in compliance with the IEEE 488.2 (syntax) standard. It is intended to give you enough basic information about the IEEE 488.2 Standard to successfully program the Logic Analysis System. You can find additional detailed information about the IEEE 488.2 Standard in ANSI/IEEE Std 488.2-1987, IEEE Standard Codes, Formats, Protocols, and Common Commands.

The HP 16500C Logic Analysis System is designed to be compatible with other Hewlett-Packard IEEE 488.2 compatible instruments. Instruments that are compatible with IEEE 488.2 must also be compatible with IEEE 488.1 (HP-IB bus standard); however, IEEE

488.1compatible instruments may or may not conform to the IEEE

488.2standard. 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 chapter 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-232-C program messages and response messages for the HP 16500C Logic Analysis System are structured very similar to those described by IEEE 488.2. In most cases, the same structure shown in this chapter for IEEE 488.2 will also work for RS-232-C. Because of this, no additional information has been included for RS-232-C.
