Abbreviating commands, queries, and parameters
You can abbreviate most SCPI commands, queries, and parameters to an accepted short form. This
manual shows these commands as a combination of upper and lower case letters. The upper case
letters indicate the accepted short form of a command, as shown in the following figure. The accepted
short form and the long form are equivalent and request the same action of the instrument.
