NOTE
Ensure that the antenna is located as close to the back of the receiver as
possible. Depending on the antenna used, the signal will be very small
(–100 dBm or smaller). When positioning the antenna, do not move it
too quickly as the analyzer is doing a three cycle average and the peak
will build. If you do not see a signal, change the center frequency up or
down by 1 kHz up to 4 kHz (signal should not be outside of this range).
Ensure that the resolution bandwidth does not change while doing this.
