Any two frequency setting headers 

 STOP, 

 or

SPAN) may be sent in a single message and the resulting sweep

is what was requested. The order of the headers in the message

does not make any difference in the final result. When a message is
completed, coupling equations are used to fix the unset parameters to

the correct values. These equations specify that:

center frequency = (start + stop)   2

frequency span = (stop   start)

If more than two are sent then the last two in the message are used
to determine the sweep and no errors are given.

If only one header is sent in a message, then the assumed pairs are
center/span and start/stop. In other words, if only center is sent,
then span is kept constant (if possible) while adjusting center to the
requested value. The start/stop frequencies are updated to reflect the
changes based on the coupling equations.
