Note the use of the optional header LEVel to maintain the correct path
within the voltage and current subsystems, and the use of the root
specifier to move between subsystems.
Including Common Commands
You can combine common commands with subsystem commands in the
same message. Treat the common command as a message unit by
separating it with a semicolon (the message unit separator). Common
commands do not affect the header path; you may insert them anywhere
in the message.

Case sensitivity
Common commands and SCPI commands are not case sensitive. You
can use upper or lowerfor example:
*RST = *rst
:DATA? = :data?
:SYSTem:PRESet = :system:preset
Long-form and short-form versions
A SCPI command word can be sent in its long-form or short-form version.
The command subsystem tables in Section 5 provide the in the
long-form version. However, the short-form version is indicated by upper
case characters. Examples:
:SYSTem:PRESet long-form
:SYST:PRES short form
:SYSTem:PRES long-form and short-form combination
Note that each command word must be in long-form or short-form, and
not something in between.
For example, :SYSTe:PRESe is illegal and will generate an error. The
command will not be executed.
Query
Observe the following precautions with queries:
⚫ Set up the proper number of variables for the returned data. For example, if
you are reading back a measurement array, you must dimension the array
according to the number of measurements that you have placed in the
measurement buffer.
⚫ Read back all the results of a query before sending another command to
