Carefully adjust the spectrum analyzer to center the transmitter
spectrum.
As the spectrum analyzer's frequency span is reduced and the flat top of
the spectrum fills the spectrum analyzer display, it is extremely impor-
tant to keep the spectrum display (with carrier signal if any) centered
so that the carrier signal (if any) will remain visible as the span is
reduced.
