Command Reference
This chapter contains reference information on programming AT525D with
the SCPI commands.
This chapter provides descriptions of all the AT525D's available RS-232 commands which
correspond to Standard Commands for Programmable Instruments (SCPI) command sets,
listed in functional subsystem order.

Notation Conventions and Definitions
The following conventions and definitions are used in this chapter to describe
RS-232 operation.
< > Angular brackets enclose words or characters that are used to symbolize a
program code parameter or an RS-232 command.
[ ] A square bracket indicates that the enclosed items are optional.

Command Structure
The AT525D commands are divided into two types: Common commands and
SCPI commands.
The common commands are defined in IEEE std. 488.2-1987, and these
commands are common for all devices. The SCPI commands are used to control
all of the AT525D's functions.
The SCPI commands are tree structured three levels deep. The highest level
commands are called the subsystem commands in this manual. So the lower
level commands are legal only when the subsystem commands have been
selected.
A colon (
:
) is used to separate the higher level commands and the lower level
commands.
Semicolon (;) A semicolon does not change the current path but separates two
commands in the same message.
