Uplink Channel Types
In uplink mode, channel type for channels 2 and 3 is set by channel 1, but each channel
can be turned off independently via its own state command.
The following uplink channel types are assigned by appending the
[:SOURce]:RADio:WCDMa[:BBG]:ULINK:CHANnel[1]:TYPE command with one of the
following variables:
ACCH Sets the uplink channel type to an Associated Control Channel (ACCH).
DA Sets the uplink channel type to a Dedicated Traffic Channel plus
Associated Control Channel (DTCH+ACCH).
DTCH Sets the uplink channel type to a Dedicated Traffic Channel (DTCH).
DTX Sets the uplink channel type to a Discontinuous Transmission Channel
(DTX).
RACH Sets the uplink channel type to a Random Access Channel Long
(RACH-L).
SDCCH Sets the uplink channel type to a Stand-Alone Dedicated Control Channel
(SDCCH).
UPCH Sets the uplink channel type to a User Packet Traffic Channel (UPCH).
