Adjacent Channel Power Measurement: Main CH Power, Left channel power and Right channel power.

◆ Main CH Power: display the power within the bandwidth of the main power

◆ Left channel power : display 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 Frequency

Sets the center frequency, this center frequency which is the same with the center frequency of the

analyzer. Modifying this parameter will change the center frequency of the analyzer.

2. Main channel bandwidth

Set the bandwidth of the main channel and the power of the main channel is the power integral within

this bandwidth. You can use the numeric keys, knob and direction keys to modify this parameter.
