Carrier-to-Interference Ratio
Calculates the ratio of the carrier signal power to the power level of the noise
and interference signals.
To determine the ratio, two measurements need be done. First sweep should
be the carrier and interferer. The second sweep should be the interferer alone.
Note:
Because the transmitted carrier must be turned off for the
second portion of this measurement, access to the transmitter is
needed to complete this procedure.
1.
Do one of the following:
Move marker to the desired frequency.
Note:
The default marker placement assumes the carrier to be
measured is the center of the frequency span. It can be moved via
the arrow keys and/or wheel.
Select Marker to Max Peak to quickly identify the signal to be
measured.
2.
Measure the carrier signal.
3.
Turn off the transmitter.
4.
Measure the noise and interference signal levels as follows:
Note:
The carrier power and interferer power will be displayed in
selected power units, and the ratio in dB.
