Query Responses
Figure 7-2 Numeric Value Query Response
Commands that set a function to a numeric value can be queried to
determine the current setting of that function. For example, the CF
command sets the center frequency to a numeric value in hertz. The
format for the response to a CF query command is shown above. Refer
to Table on page 372 for definitions of syntax elements.
Figure 7-3 Binary State Query Response
Other commands that control the binary state (on or off) of a function
can also be queried to determine its state. Examples are commands
that accept ON and OFF parameters such as the ANNOT or GRAT
commands. The query response in this case, as shown above, is either
zero (indicating that the queried state is off or inactive) or one
(indicating that the queried state is on or active). As an example, GRAT?
will return a zero if the display graticule is off, and a one if it is on.&&
Syntax elements are shown in the syntax diagrams as elements within
rectangles.
