Network Standard Margin
Display of an appropriate correction factor for the reference power, accounting for an
expected crest factor of the RF input signal. The network margin depends on the
typical signal shape and the typical power measurements in the network.
In general, it is not possible to predict the crest factor for WCDMA UL signals and
WCDMA conformance tests with good accuracy. Consequently, no network margin
(corresponding to a value of 0 dB) is used. It is recommended to choose the "Expected
Nominal Power" as the peak power of the measured signal; see above.
9.2.1.3 UE Signal Info
The "UE Signal Info" parameters describe properties of the measured uplink WCDMA
signal that the R&S CMW 500. needs for synchronization and decoding.
Multi evaluation configuration: UE Signal Info
Scrambling Code
Number of the long code that is used to scramble the uplink WCDMA signal. The
scrambling code number must be in the range 0 to FFFFFF (hex) corresponding to 0 to
16777215 decimal.
GPIB command: CONFigure:WCDMa:MEASurement<i>:UESignal:SCODe
UL DPCCH Slot Format
Uplink DPCCH slot format in the range between 0 and 5. The slot format defines the
length of the individual data fields in the DPCCH. The multi-evaluation measurement
can be performed with arbitrary UL slot formats, including the slot formats with variable
transport format (1, 3, 4).
GPIB command: CONFigure:WCDMa:MEASurement<i>:UESignal:SFORmat
Network Mode
Active channel types in the UL WCDMA signal. The R&S CMW 500 can measure a
signal carrying a single DPCH according to standard 3GPP/FDD, release 99.
GPIB command: CONFigure:WCDMa:MEASurement<i>:UESignal:ACHannels?
UL DPDCH Available
Presence of a DPDCH in the UL DPCH signal. The R&S CMW 500 can measure
a signal containing a single DPCCH (box cleared) or one DPCCH plus one DPDCH
(box selected).
