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 difference between the left
channel and the main channel (in dBc)
Right channel power: Display the power of the right channel and the power difference 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
Set the center frequency. The center frequency is the same with the center frequency of the analyzer
display. Modifying this parameter will change the center frequency of the analyzer.
2.
Main Channel
Set the bandwidth of the main channel and the power of the main channel is the power integral within
this bandwidth.
