W-CDMA Revision Information
Receiver Measurements
• Loopback bit error ratio (BER). This measurement uses the UE in loopback mode 1 to test the sensitivity of
its receiver. The receiver sensitivity test is described in 3GPP TS 34.121, section 6.2, v3.2.0, Reference
Sensitivity Level. When using the test set's FDD Test operating mode, the user must configure the UE in
the loopback mode 1 to perform this measurement; no provision is made to send messages over the
downlink signal to the UE to configure it. See
Other Features
Base Station Emulation in FDD Test Operating Mode Base station emulation for this release is limited
to sending a configurable downlink signal that the UE can synchronize to in order to transmit a corresponding
uplink signal. The downlink does not send any commands to the UE to configure it for testing. All control of
the UE must be provided by the user.
Downlink signal parameters that can be configured include the following settings:
• Downlink channel codes:
— Primary Scrambling Code
— PICH Channelization Code
— DPCH 12.2 RMC Channelization Code
• Downlink channel levels:
— FDD Test CPICH Level
— FDD Test P-CCPCH/SCH Level
— FDD Test PICH Level
— FDD Test DPCH Level
• Orthogonal Channel Noise Simulator - OCNS is automatically turned on and off, and the level set, as the
downlink channel levels are changed. See
• Additive White Gaussian Noise (AWGN)
• Downlink Transport Format Combination Indicator (TFCI)
• Downlink channel
• Downlink DTCH data type
• Downlink PICH data pattern
Power control bit patterns can also be configured on the downlink. This allows you to vary the value being sent
for the uplink closed loop power control data, and to send step up and step down power control sequences.
CW Operating Mode CW operating mode provides an unmodulated RF generator signal with an adjustable level from
-10 dBm to -127 dBm.
