Parameters
PredefExp is one of the following predefined expressions: STEP1|STEP2
Default is STEP1
.
Description
This command selects the TPC algorithm step size for the inner loop power control
algorithm.
Query
The query form of this command will return the current selected inner loop power
control algorithm step size.
Example
:CONF:WCDM:MEAS:RFTX:INNE:STEP STEP2
:CONF:WCDM:MEAS:RFTX:INNE:STEP?
Value returned in this example: "STEP2"
.

<PredefExp>
Parameters
PredefExp is one of the following predefined expressions: NORMal|SINGle
Default is NORMal
.
Description
This command sets the mode of the inner loop power control algorithm.
Query
The query form of this command will return the current selected mode for the inner
loop power control algorithm.
Example
:CONF:WCDM:MEAS:RFTX:INNE:MOD SING
:CONF:WCDM:MEAS:RFTX:INNE:MOD?
Value returned in this example: "SING"
.
Syntax
:CONFigure:WCDMa:MEASure:RFRX:SYNChronise
Parameters
There are no parameters.
Description
This command will synchronise the 4400 to the data looped back from the mobile.
The command has to be executed on a normal output level before measuring the Bit
Error Rate or the Block Error Rate.
Query
The query form of this command returns whether the 4400 could synchronise to the
data from the mobile or not. If it is synchronised, the output level can be changed to
low values and a Bit/Block Error Rate can be measured.
Example
:CONFigure:WCDMa:MEASure:RFRX:SYNChronise
:CONFigure:WCDMa:MEASure:RFRX:SYNChronise?
Value returned in this example "ON"
.
Syntax
:CONFigure:WCDMa:MEASure:RFRX:NBLOck <Int1>
Parameters
Int1 is an integer number. The minimum value is 10, the maximum value 4096.
The default value is 40.
Description
This command sets the number of blocks to use in the BER/BLER test.
Query
The query form of this command will return the current setting of the Willtek 4400.
