:CALCulate:WCDMa:RFSPectrum:MSPectrum:VALue
:CALCulate:WCDMa:RFSPectrum:MSPectrum:MAXPeak
Description
This command sets the lower limit for the peak code domain error measurement. The
physical dimension of the number stated is dB.
Query
There is a query form which returns the stored settings.
Example
:CALC:WCDM:RFTX:COD:PCD:LIM:LOW -99.0
:CALC:WCDM:RFTX:COD:PCD:LIM:LOW?
Returns -99.0
.
Syntax
:CALCulate:WCDMa:RFSPectrum:MSPectrum:VALue <real1>
Parameters
real1 is a floating point real number. The minimum value is -5,000,000.0, the
maximum is 5,000,000.0. The minimum resolution possible is 0.1
.
Description
There is only a query form of this command available.
Query
The query form of this command delivers an (interpolated) measurement result value
of the modulation spectrum curve at the frequency specified with the real1 param-
eter. real1 is interpreted as an offset from the carrier (i.e. the transmission fre-
quency). The string returned will contain one floating point real number. The physical
dimension of the measurement result value returned is 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:MSP:AVG command to do so.
–The :CALC:WCDM:RFSP:MSP:VAL
command is not really a measurement -
it is an interpolation of the spectrum curve for the frequency specified.
Example
:MEAS:WCDM:RFSP:MSP:AVG 20
:CALC:WCDM:RFSP:MSP:VAL? -50000
This command will interpolate a modulation spectrum measurement at an offset of
50 kHz to the carrier. The value returned in this example is:
"-4.7".
Syntax
:CALCulate:WCDMa:RFSPectrum:MSPectrum: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:MSP: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.
