available as a diagnostic function, to check the operation of the
alignment signal in the case of alignment failure. Once selected, a

be selected. Because the alignment signal is input at the IF
frequency, it is displayed on any active Spectrum (Freq Domain)
window, regardless of center frequency.

alignment signal. This is available as a diagnostic function, to check
the operation of the alignment signal in the case of alignment
failure. Because the alignment signal is input at the IF frequency, it
is displayed on any Spectrum (Freq Domain) window.

front-panel key.
