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 synthesizer. For a complete listing of the programming codes see “SCPI Command Summary” in the Operating and Programming Reference chapter that follows.
