Measurement Results: Main CH Power, Left channel power and Right channel power.
 Main CH Power: Displays the power within the bandwidth of the main power
 Left channel power : Displays the power of left channel and the power dierence between the left
channel and the main channel (in dBc)
 Right channel power: Display the power of the right channel and the power dierence between the
right channel and the main channel(in dBc)
Measurement parameter: Center frequency, main channel bandwidth, adjacent channel bandwidth
and channel spacing
1. Center Freq
