Command Syntax
Figure 1: Command message elements

Commands

Commands cause the instrument to perform a specific function or change one of
its settings. Commands have the structure:
[:]<Header>[<Space><Argument>[<Comma><Argument>]...]
A command header is made up of one or more mnemonics arranged in a
hierarchical or tree structure. The first mnemonic is the base or root of the tree
and each subsequent mnemonic is a level or branch off of the previous one.
Commands at a higher level in the tree may affect those at a lower level. The
leading colon (:) always returns you to the base of the command tree.

Queries

Queries cause the instrument to return information about its status or settings.
Queries have the structure:
[:]<Header>
[:]<Header>[<Space><Argument>[<Comma><Argument>]...]
You can specify a query command at any level within the command tree unless
otherwise noted. These branch queries return information about all the
mnemonics below the specified branch or level.
For example, MEASUrement:MEAS<x>:UNIts? returns the measurement units,
while MEASUrement:MEAS<x>:TYPe? returns the measurement type selected
for the measurement, and MEASUrement:MEAS<x>? returns all the
measurement parameters for the specified measurement.
