Use of the Command Tables
In Table 1-4, notice that a new column titled “Allowed Values” has
been added to the command table. This column lists the specific
values or range of values allowed for each parameter. A vertical bar
(I)
separates values in a list from which you must choose one value.
The commands listed in the table are only part of all the available
SCPI commands of the swept CW generator. For a complete listing
of the programming codes see “SCPI Command Summary” in
Chapter 2.
