Query commands

This type of command requests (queries) the presently programmed status. It is identified
by the question mark (?) at the end of the fundamental form of the command. Most com-
mands have a query form:
:ARM:TIMer?
Most commands that require a numeric parameter (<n>) can also use the DEFault,
MINimum, and MAXimum parameters for the query form. These query forms are used to
determine the *RST default value and the upper and lower limits for the fundamental com-
mand. Examples are:
:ARM:TIMer? DEFault
:ARM:TIMer? MINimum
:ARM:TIMer? MAXimum
Case sensitivity
Common commands and SCPI commands are not case sensitive. You can use upper or
lower case and any case combination. Examples:
*RST
:DATA?
:SYSTem:PRESet
NOTE
Using all upper case will result in slightly faster command response times.
