Sync Type BTS
Accesses the menu that enables you to select the channel to synchronize with, and to set features, such
as Symbol Rate, that may affect synchronization. You can select from the following types of channels and
features listed in the menu:
•
CPICH - Synchronize with the common pilot channel (CPICH).
•
Pilot-aided Timing Est(imator) - Enables additional symbol timing estimation to each detected code
channel through the demod calculation process by referring to the pilot channel (CPICH) timing
correlation.
•
SCH - Synchronize with the synchronization channel (SCH).
•
Symbol Based - Allows you to access the menu that allows you to select the code symbol to
synchronize with.
•
Symbol Rate - Allows you to set the symbol rate, ranging from 7.5 to 960 ksps. The parameter
automatically sets the maximum value for Code Number when appropriate.
•
Code Number - Allows you to set the code number. The range is 0 to 511, depending on the Symbol
Rate setting.
•
Antenna–2 CPICH - Allows you to synchronize with the STTD Antenna–2 common pilot channel.
•
Pilot-aided Timing Est(imator) - Enables additional symbol timing estimation to each detected code
channel through the demod calculation process by referring to the pilot channel (Antenna–2 CPICH)
timing correlation.
•
STTD Diff - Allows you to synchronize to the common pilot channel at STTD antenna–1 and antenna–2
to make Diversity Time Error measurements.
•
TSTD SCH Antenna1 – Allows you to synchronize the antenna1 of TSTD SCH.
•
TSTD SCH Antenna2 – Allows you to synchronize the antenna2 of TSTD SCH.
