Comments • The "Aux In" BNC is a multiple-use input: for FSK control, for
waveform hopping control, as a reference oscillator source, for
reference oscillator gating, or as a start arm source. Only one of
these uses may be active at any time.

The legal range for
freq_span, as well as the MINimum and MAXimum values,
are context-dependent. See the section “Coupling Rules” at the beginning of
the SOURce:FREQuency subsystem for a description of the coupling between
STARt, STOP, CENTer, and SPAN.
