WCA230A & WCA280A Programmer Manual
The Line Feed (LF) character (ASCII 10), and all characters in the range of
ASCII 127-255 are defined as special characters. These characters are used in
arbitrary block arguments only; using these characters in other parts of any
command yields unpredictable results.
You can abbreviate most SCPI commands, queries, and parameters to an
accepted short form. This manual shows these short forms as a combination of
upper and lower case letters. The upper case letters indicate the accepted short
form of a command. As shown in Figure 2--2, you can create a short form by
using only the upper case letters. The accepted short form and the long form are
equivalent and request the same action of the instrument.

NOTE
. The numeric suffix of a command or query may be included in either the
long form or short form; the analyzer will default to “1” if no suffix is used. In
Figure 2--2, the “3” of “CALC3” indicates that the command is directed to
View 3.
