Chapter 4 Command Reference

Introduction

Introduction

This chapter describes the SCPI Subsystem commands and the IEEE 488.2 Common commands for the HP 53131A/132A 225 MHz Universal Counter. The information in this chapter will help you program the Counter over the HP-IB.

The commands are presented in alphabetical order.

∙SCPI Subsystem commands are described on pages 4- 4 thru 4-121.

∙IEEE 488.2 Common command descriptions start on page 4-122.

∙Device Clear and Group Execute Trigger descriptions are also included on pages 4-31 and 4-42, respectively.

For each command description:

∙where the phrase “Sets or queries” is used, the command setting can be queried by omitting the parameter and appending a “?” to the last command keyword.

For example,

:INPut:COUPling [AC DC]

can be queried with

:INPut:COUPling?

∙unless otherwise noted, a command described as an event cannot be queried.

∙unless otherwise noted, the command setting is affected by save/recall.

∙the square brackets, [ ], are used to indicate that the element(s) within the brackets are optional. Note, the brackets are NOT part of the command and should not be sent to the Counter.

∙the vertical bar, , is used to mean “OR” and is used to separate alternative options.
