FDD Test Operating Mode
MS Target Power
This setting specifies the expected power level from the UE (mobile station). When using automatic receiver
control (the default setting), the test set uses the MS Target Power setting to set the input range for its
measurement and uplink receivers. If the transmitted level from the UE is above or below the range expected
by the receivers, an Under Range or Over Range message and integrity indicator are produced. This setting is
not used during manual receiver control.
This setting does not anticipate a change in UE power output when sending closed loop power control changes
or transmit power control (TPC) commands during FDD Test mode operation. It is only used to indicate the
expected power level from the UE as determined by the user. See "Receiver Control" for information on setting
the expected power level into the test set.
Transport Format Combination Indicator Pattern
The TFCI pattern tells the UE which transport formats to use for communications between the downlink
physical channels protocol layer (L1) and the medium access control (MAC) layer. In FDD Test mode, this
value does not correspond to any specific transport channel format; it is provided to allow the user to
determine if their UE is correctly decoding this value.
If the UE is configured to respond to the TFCI, this value must match the UE transport format configuration in
order for the UE to decode the downlink channels and synchronize to the test set. See "CALL:FDDTest" .
Power Control Settings
Power control commands can be sent by specifying the uplink closed loop power control data or by sending
transmit power control (TPC) step up/step down bit patterns. However, the user must verify that the UE
correctly decoded the power control data, either by verifying that the power level from the UE did change or by
looking at the UE decoded downlink data. If the UE power output does change in response to the change order,
the user must change the test set's expected power level (MS Target Power) when making measurements that
do not use autoranging. See "MS Target Power" . See also "CALL[:CELL]:CLPControl:UPLink" and
"CALL:FDDTest:CLPControl:UPLink:MODE" for a description of the GPIB commands for power control.
Paging Indicator Settings
Downlink paging indicator channel data can be set to all ones or all zeroes. However, the user must verify that
the UE has correctly decoded the page indicator data. See "CALL:PICHannel:DATA" .
Traffic Channel (DTCH) Data
Downlink dedicated traffic channel (DTCH) data of various types can be sent. To determine if the UE has
correctly decoded the data stream, you can use the test set's loopback bit error ratio measurement or use your
UE built in bit error reporting (if available). See "CALL:DTCHannel:DATA" .
Downlink Channel
When the RF generator frequency control (RF Gen Freq Ctrl) is set to auto, the downlink channel setting
automatically adjusts the center frequency for the test set's RF generator based on the specified channel
number. See "CALL:CHANnel" .
