NOTE If a GPS time reference is unavailable, you must connect to the even second pulse

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” on page 198.

Performing a Basic CDMA Transmitter Measurement

Once you have taken the base station out of service and made the proper
