WCDMA RF Testing Using Local Mode
Phoenix supports the following functions in local mode:
• TX control using either direct power control or uplink power control
• RX control to LNA and BB AGC. Algorithm Mode supports the RSSI measurements
WCDMA TX Control
• Two modes are available:
• Manual mode is for direct control of the AGC’s, PA Bias - and DC/DC-
converters. Also, modulation type, channel settings and different kinds of
sweeps with DACs can be run to study the phones behaviour
• Algorithm mode can be used when TX (AGC’s) are calibrated. Output
power can be set to fixed power levels or power sweeps can be run. Also
WCDMA signal code settings (scrambling and channelisation codes can
be modified).
• WCDMA TX control can be activated from Phoenix-menu:
Testing/WCDMA/Tx Control
• Manual mode:
DA-converter setting for AGC’s in TEX and HEX (0…1023 )
DA-converter for PA bias control ( 0…12 )
DA-converter setting for DC/DC-converter ( 112 … 512;
112 DAC~1.5 V DC/DC output voltage, 512 DAC ~3.3V )
Modulation selection is for WCDMA Signal or CW Signal
Here the uplink data- and control channel weighting can
be adjusted ( 0…15 )
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.
