:CALCulate:WCDMa:RFSPectrum:ACLR:LIMit:LOWer:[DATA]
:CALCulate:WCDMa:RFSPectrum:SEM:LIMit[:FAIL]
:CALCulate:WCDMa:RFSPectrum:SEM:LIMit:STATe
Parameters
Realx
are floating point real numbers. The minimum value for the parameters is
-120.0, the maximum is 0.0, the resolution is 0.1, the default value is for
Real1
-33.0, for Real2 -43.0 and for Real3 -50.0.
Description
This command sets the upper limits for the adjacent channel leakage power ratio
measurement. Real1 represents the 5 MHz lines in dBc and Real2 represents the
10 MHz lines also in dBc. Real3 represents the minimum power of the center fre-
quency in dBm where this upper limits are valid.
Query
There is a query form which returns the stored settings.
Example
:CALC:WCDM:RFSP:ACLR:LIM:UPP -20.0,-25.0,-70.0
:CALC:WCDM:RFSP:ACLR:LIM:UPP?
Returns -20.0,-25.0,-70.0
.
Syntax
:CALCulate:WCDMa:RFSPectrum:ACLR:LIMit:LOWer:[DATA]
<Real1>,<Real2>
Parameters
Realx
are floating point real numbers. The minimum value for the parameters is -
120.0, the maximum is 0.0, the resolution is 0.1, the default value is for both
values -120.0
.
Description
This command sets the lower limits for the adjacent channel leakage power ratio
measurement. The physical dimension of the number stated is dBc. Real1 represents
the 5 MHz lines and Real2 represents the 10 MHz lines.
Query
There is a query form which returns the stored settings.
Example
:CALC:WCDM:RFSP:ACLR:LIM:LOW -60.0,-65.0
:CALC:WCDM:RFSP:ACLR:LIM:LOW?
Returns -60.0,-65.0
.
Syntax
:CALCulate:WCDMa:RFSPectrum:SEM:LIMit[:FAIL]?
Parameters
There are no parameters.
Description
There is solely a query form of this command available.
Query
This command delivers a boolean number in a string which indicates if the adjacent
channel leakage power ratio measurement exceeds the limits.
Example
:MEAS:WCDMA:RFSP:SEM:AVG? 20
:CALC:WCDM:RFSP:SEM:LIM?
Returns 0 if the average spectrum line is within the template limits, otherwise 1.
Syntax
:CALCulate:WCDMa:RFSPectrum:SEM:LIMit:STATe <PredefExp>
Parameters
PredefExp
is one of the following predefined expressions: ON|OFF. Default is ON.
Description
This command switches the check of the measurement result values of the spectrum
emission mask measurement against their user-definable limits either ON or OFF.
