Common CDMA Tx Analyzer Measurements

Preparing to Make CDMA Tx Analyzer Measurements
The first step in measuring CDMA transmitter performance is to take the base station out of service. The next step is to choose the type of time reference available. The measurement configuration depends upon the type of time reference you choose to use. Optimally, a GPS time reference is desired. GPS provides an independent time reference that can help determine if the base station under test is synchronized with the rest of the network. Base stations not synchronized with the rest of the network are referred to as "island cells".

NOTE: If a GPS time reference is unavailable, you must connect to the even second pulse from the base station.

You must also know the channel or frequency and the PN (pseudo noise) Offset of the CDMA signal to be analyzed. Each base station sector has a unique PN Offset. For more information on PN Offsets refer to "Adding a Marker"
