Adjacent Channel Power
Using the Adjacent Channel Power Measurement
Adjacent Channel Power
power is +20 dBm (100 mW). When directly coupled to a base station (BTS) or
Access Network (AN), the test set can be damaged by excessive power applied to
any of these three ports.
To prevent damage in most situations when you directly couple the test set to a base
station, use the high power attenuator between the test set and the BTS.
NOTE The lowest level the signal generator can go to is -90 dBm. In order to get a lower
level, you must use an external attenuator. You can compensate for the attenuator
using RF Out Loss.
