BND LOCK
ON OFF
locks the spectrum analyzer onto a selected frequency band (local
oscillator harmonic number). When only one frequency band is being swept
the corresponding
softkey
will be underlined, even if band lock is off.
Note
When using the spectrum analyzer in a band lock mode, the span is limited
to 3.6
GHz
in band 0 and 1, and to 7
GHz
in bands 2 through 4. To select the
maximum span in a given band, use the start frequency, stop frequency, or
span function.
