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:
TRIGger: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:
TRIGger:TIMer? DEFault
TRIGger:TIMer? MINimum
TRIGger: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
Angle brackets (< >) are used to denote a parameter type. Do
not include the brackets in the program message. For example:
RATio <b>
The <b> indicates a Boolean-type parameter is required.
Therefore, to enable channel ratio, you must send the com-
mand with the ON or 1 parameter as follows:
RATio ON
RATIO 1
= *rst
= data?
= system:preset
Using all upper case will result in slightly faster command response times.
Queries the timer interval.
Queries the *RST default value.
Queries the lowest allowable value.
Queries the largest allowable value.
