:CALCulate:WCDMa:RFSPectrum:SEM:MAXPeak
:CALCulate:WCDMa:RFRX:BER:LIMit[:FAIL]
:CALCulate:WCDMa:RFRX:BER:LIMit:STATe
Syntax
:CALCulate:WCDMa:RFSPectrum:SEM:MAXPeak?
Parameters
There are no parameters.
Description
There is only a query form of this command available.
Query
The query form of this command delivers the frequency offset (in Hz) from the carrier
and the maximum value of the measured modulation spectrum curve. The string
returned will contain two floating point real numbers. The physical dimension of the
measurement result values returned is for the first value Hz and for the second value
dBc.
Notes
– Please note that you need to have a spectrum measurement taken before this
command will return any meaningful result. We recommend to use the
:MEAS:WCDM:RFSP:SEM:AVG command to do so.
–The
:CALC:WCDM:RFSP:MSP:MAXP command is not really a measurement -
it is an readout of the spectrum curve.
Example
:MEAS:WCDM:RFSP:SEM:AVG 20
:CALC:WCDM:RFSP:SEM:MAXP?
This command will read at the modulation spectrum measurement maximum the fre-
quency offset to the carrier and the measurement result value. The values returned in
this example is: "-67700.0,-5.2"
.
Syntax
:CALCulate:WCDMa:RFRX:BER:LIMit[:FAIL]?
Parameters
There are no parameters.
Description
There is only a query form of this command available.
Query
This command delivers a boolean number in a string which indicates if the
:MEAS:WCDMA:ARR:RFRX:BER measurement violated the defined limits.
Example
:MEAS:WCDMA:ARR:RFRX:BER 20
:CALC:WCDM:RFRX:BER:LIM?
The query returns 1 if any of the 20 measurement results was out of limits, or 0 if
none of the results was out of limits.
Syntax
:CALCulate:WCDMa:RFRX:BER:LIMit:STATe <PredefExp>
Parameters
PredefExp can take on one of the following values: ON|OFF. The default is ON.
Description
This command switches the check of the measurement result values of the BER mea-
surement against their user-definable limits either ON or OFF.
Query
There is a query form which returns the stored settings.
Example
:CALC:WCDM:RFRX:BER:LIM:STAT ON
Switches the limit check for the BER measurement on.
