n Semicolon
A semicolon separates two commands in the same message without
changing the current path.
w
Whitespace
White space characters, such as <tab> and <space>, are generally
ignored. There are two important exceptions. White space inside a
keyword, such as
:FREq
uency,
is not allowed. You must use white
space to separate parameters from commands. For example, the
<space> between LEVel and 6.2 in the command
:POWer
: LEVel
6.2 is mandatory. White space does not affect the current path.
w
Commas
If a command requires more than one parameter, you must
separate adjacent parameters using a comma. Commas do not
affect the current path.
w
Common Commands
Common commands, such as
*RST,
are not part of any subsystem.
An instrument interprets them in the same way, regardless of the
current path setting.
