Command Reference
This chapter provides descriptions of all the FM8116R's available RS-232 commands which correspond to
Standard Commands for Programmable Instruments (SCPI) command sets, listed in functional subsystem
order.

Command Structure
The FM8116R 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 FM8116R'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.
