RFGenerator subsystem
The RFG subsystem controls the accessible parameters of the RF generator.
Important notes:
– The RF generator can only be used if all communication systems have been
switched off (and unloaded) before.
– The RF generator fuctionality of the 4400 will enable you to provide a base
channel to allow the mobile under test to synchronize to the base station.
However, as long as the RF generator is active, there will be no call setup
and no reaction to signaling.
Some of the data transmitted by the 4400 in the base channel can be set or
altered using the SCPI commands described in section “CONFigure
subsystem” on page 297.
Query
There is a query form which returns the stored settings.
Example
:CALC:WCDM:RFRX:BLER:LIM:STAT ON
Switches the limit check for the Bler measurement on.
Syntax
:CALCulate:WCDMa:RFRX:BLER:LIMit:UPPer:[DATA] <real>
Parameters
real is a floating point real number. Its minimum value is 0.0, the maximum is
100.0, the resolution is 0.1 and the default is 0.1.
Description
Sets the upper limit for the mobile's Block Error Rate. The physical dimension of the
number is stated as a percentage.
Query
There is a query form which returns the stored settings.
Example
:CALC:WCDM:RFRX:BLER:LIM:UPP 2.5
:CALC:WCDM:RFRX:BLER:LIM:UPP?
Returns 2.5.
Syntax
:CALCulate:WCDMa:RFRX:BER:LIMit:LOWer:[DATA] <real>
Parameters
real is a floating point real number. Its minimum value is 0.0, the maximum is
1.0, the resolution is 0.1 and the default is 0.0.
Description
Sets the lower limit for the mobile's Block Error Rate. The physical dimension of the
number is stated as a percentage.
Query
There is a query form which returns the stored settings.
Example
:CALC:WCDM:RFRX:BLER:LIM:LOW 0.0
