Query Commands; Case Sensitivity; Long-Form And Short-Form Versions - Keithley 2010 User Manual

Query commands

The Query command requests 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?
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.
:TRIGger:TIMer?
:TRIGger:TIMer?
:TRIGger:TIMer?

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 = :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 are in the long-form version. However, the short-form version is
indicated by upper case characters.
:SYSTem:PRESet
:SYST:PRES
:SYSTem:PRES
Note that each command word must be in either long-form or short-form. For example,
:SYSTe:PRESe is illegal and will generate an error. The command will not be executed.
Queries the timer interval
DEFault Queries the *RST default value
MINimum Queries the lowest allowable value
MAXimum Queries the largest allowable value
