Predefined Channel Tables
Predefined channel tables offer access to a quick configuration for the channel search. The 1xEV-DO
BTS Analyzer option provides the following set of channel tables compliant with the 1xEV-DO
specification:
• DPQPSK:
Channel table with channel types PILOT/MAC/PREAMBLE/DATA with modulation type QPSK in
channel type DATA and the following listed active codes in channel types.
• DO8PSK:
Channel table with channel types PILOT/MAC/PREAMBLE/DATA with modulation type 8–PSK in
channel type DATA and the following listed active codes in channel types.
• DO16QAM:
Channel table with channel types PILOT/MAC/PREAMBLE/DATA with modulation type 16–QAM in
channel type DATA and the following listed active codes in channel types.
• DO_IDLE:
Channel table with channel types PILOT/MAC – known as IDLE slot, since it does not contain any
active channels in the DATA channel type.
