The Receive Power Scan window enables the user to scan the entire FM band to find one or more candidate
channels on which to transmit, where candidate channels are defined as those with the lowest received power.
Selecting WindowPower Scan will launch the Receive Power Scan Window as shown in Figure 43. The band
and channel spacing can be selected and the number of regions can be set to return one to ten candidate
channels. The number of channels to average can be set to 1, 3, 5, or 7. Selecting “To Presets “will save the
candidate channels to the GUI presets. Refer to "AN307: Si4712/13/20/21 Receive Power Scan" for additional
