Configuring AM
Using this procedure, you will learn
how to create a multipath ampli-
tude-modulated RF carrier with the
following characteristics:
•RF output frequency set to 4 GHz
•RF output amplitude set to 0 dBm
•AM Path 1 depth set to 90 percent
•AM Path 1 rate set to 10 kHz
•AM Path 1 waveform set to sine
•AM Path 2 depth set to 40 percent
•AM Path 2 waveform set to
triangle
•AM Path 2 rate set to 5 kHz
