Model 2701 User’s Manual Remote Operations 10-23
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
commands have a query form:
TRIGger:TIMer? Queries the timer interval.
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
command. Examples are:
TRIGger:TIMer? DEFault Queries the *RST default value.
TRIGger:TIMer? MINimum Queries the lowest allowable value.
TRIGger:TIMer? MAXimum Queries the largest allowable value.
Case sensitivity
Common commands and SCPI commands are not case sensitive. You can use upper or
lower case and any case combination. Examples:
*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 15 provide 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.
