SCPI (Standard Command for Programmable Instruments) is an ASCII-based instrument command
language used in test and measurement instruments. SCPI commands are based on a hierarchical
structure (also known as a tree system). In this system, related commands are grouped under a
common node or root, thus forming a subsystem.
According to the command syntax, most commands (and some parameters) are represented by a
mixture of uppercase and lowercase letters. Uppercase letters indicate the abbreviation of the
command. For shorter program lines, you can send commands in abbreviated format. If you want
better program readability, you can send long format commands.
Note: In order to avoid misunderstanding of instruction abbreviations, the TH34XX series try
to avoid too many abbreviations in instruction descriptions. Most of the instruction
descriptions will be described directly in abbreviations.
Grammatical conventions:
[SOURce[1|2]:]VOLTage:UNIT {VPP|VRMS|DBM}
[SOURce[1|2]:]FREQuency:CENTer {<frequency>|MINimum|MAXimum|DEFault}
Note: Command syntax conventions:
 The braces ({ }) contain the parameter options for the given command string. Braces are not
sent with the command string.
 A vertical bar (|) separates multiple parameter selections for a given command string. For
