Select one of the markers in the Tune with drop-down list and then set the location of the
marker to the frequency you want to demodulate. If the marker you select is not enabled, the analyzer will
tune to the frequency the marker was last set to.
Receiver BW
The Receiver BW setting will not change the acquisition bandwidth. Thus, if the acquisition bandwidth
is too narrow, audio demodulation will be disabled. The following three cases illustrate the relationship
between the Acquisition BW, Receiver Frequency, and Receiver BW.
Case 1.
In this case, the upper limit of the Receiver BW exceeds the upper limit of the acquisition
bandwidth. When this occurs, audio demodulation is disabled and an error message is displayed.
Case 2.
In this case, the upper and lower limits of the Receiver BW exceed the upper and lower limits
of the acquisition bandwidth. When this occurs, audio demodulation will be disabled and an error
message is displayed.
