Measurement Results:
C/N, Carrier Power, Noise Power.
C/N: the ratio of Carrier Power to Noise Power.
Carrier Power: the total power of the carrier bandwidth.
Noise Power: the total power of the selected noise bandwidth.
Measurement Parameter:
Carrier BW, Noise BW, Freq Offset.
1. Carrier BW
Set the bandwidth of the carrier to be measured.

Parameter
Explanation
Default
3 MHz
Range
100 Hz ~ (2*span - 2*|Freq Offset| - Noise BW)
Unit
GHz, MHz, kHz, Hz
Knob Step
Carrier BW /10, the minimum is 1 Hz
Direction Key Step
In 1-1.5-2-3-5-7.5 Sequence
2. Noise BW
Set the bandwidth of the noise to be measured.
