underlining ON locks the spectrum analyzer to the lowest frequency band
(local oscillator harmonic number) containing the correct center frequency.
Start and stop frequencies will be changed if necessary. Executing a band lock
limits the spectrum analyzer tuning range to the selected harmonic number.
Selecting the
softkeys
for band 0 through band 4 turns on the band lock
function automatically.
If the start frequency is well within a lower band, turning band lock off will
result, in a multiband sweep. If a specific band had been selected prior to
changing to a multiband sweep, the selected band’s
softkey
label will no longer
be underlined indicating that it is not selected. Sweep of a single band is
indicated by the selected band’s
softkey
label being underlined.
Note
Before changing the frequency range to another harmonic band, unlock the
band by pressing BND LOCK ON OFF so that OFF is underlined.
