APPENDIX E.- CARRIER / NOISE RATIO MEASUREMENT (C/N)
Figure 47.- C/N ratio measuring range.
Example
Suppose that the video carrier level for an analogue channel, is of 10 dBmV,
from the diagram we can deduce that the measurement range is of 48 dB.
Thus, if when we carry out the measurement the C/N ratio is 54 dB the display
will show C/N > 48 dB.
On the other hand, if C/N=42 dB we will see on the display C/N = 42 dB.
