Measuring CDMA Wave’s Total Power
This section describes the method of measuring the total power of CDMA signal.
Measurement conditions: The unit used in this measurement must be usable with CDMA and output a
frequency of 916.25 MHz and a level of +10 dBm.
Use appropriate parameter values to make the measurements shown below.
CAUTION:
The maximum amount of power that can be input to the analyzer is 30 dBm (1 W). When measur-
ing a signal power whose value exceeds this limit, connect an external attenuator so the power can-
not exceed 30 dBm.
Setup
1.
Connect the unit as shown in Figure 2-85.
