The measured result is the average
power of the signal. Since the
graphic display would basically just
show a straight line, measurements
in Modulated Mode use mainly the
Numeric Display Mode.
The example shows a two channel
measurement displaying an average
power of -29.952 dBm at CH 1 and -
40.030 dBm at Ch 2.
