C/N Ratio (CNR)
Measurement Interface:
Figure 2-10 C/N Ratio Measurement Interface
Measurement Results: carrier power, noise power, and C/N ratio.
 Carrier Power: power within the carrier bandwidth.
 Noise Power: power within the noise bandwidth.
 C/N Ratio: the ratio of the carrier power to the noise power.
Measurement Parameters: average count, average mode, auto average, offset
frequency, noise BW, and carrier bandwidth.
1. Avg Number
Specifies the number of times for averaging the measurement results. You can
use the numeric keys, the knob, or arrow keys to modify this parameter; you can
also use the touch screen to modify the parameter.
