Subcarrier AM Distortion

Measures the AM distortion of the subcarrier. During signal generation, different
unwanted AM components appear. Depending on the number of segments used by the
antenna, different results are displayed in the "Distortion" view (see 

"No. of Segm"

on page 114). Note that in the data recording, all results are included, not only those
displayed in the Distortion view.

"AM 60 Hz"

Displays the AM distortion at a modulation frequency of 60 Hz

"AM 1k44(48)"

Displays the AM distortion at 1440

 

Hz (48 segments * 30

 

Hz).
