• Algorithm mode:
WCDMA RX Control
• Two modes are available: Manual or algorithm.
• WCDMA RX control can be activated from Phoenix-menu
Testing/WCDMA/Rx Control
• Received signal power measurements are possible with the algorithm mode in Rx
control.
• Rx power measurements can be activated from Phoenix-menu:
Uplink power level ( open loop power ), ( -57 … +21 dBm )
Step size (in dB’s + or - ) and step counts for power sweeps.
Sequence is for how many sweeps wanted
Step duration is the length of the step in us (max 2550 us )
Uplink scrambling code and type can be selected here
Here the uplink data- and control channelization code
numbers and weighting can be adjusted ( 0…15 ). Code
classes for those define the bit rates ( spreading factors ).
e.g. DPDCH code class 6 stands for spreading factor 60 and
8 in DPCCH is for SF 256. These SF’s are used in 12.2.kpbs
uplink voice channel.
Uplink channel number can be changed in here ( 9612 …
9888 ).
NOTE: When settings are done, they’re enabled after
pressing ”Send”. If settings are then changed ( e.g. new
channel number ) you must press ”Stop” and ”Send” again.
In manual mode the LNA with 3 different gain steps and BB
AGC can be controlled.
AFC DA-converter can be adjusted ( 0… 2047, 1024 middle
value ). NOTE: If TX control is activated the AFC control can
be done from here.
Channel number for downlink can be set here ( 10562 …
10838 )
RX control can be activated by pressing ”Update”. Again if
changes are made into settings, they are valid after
pressing ”RF Stop” then ”Update”
NOTE: ”RF Stop” also disables TX control if that was active !
