:MEASure:EGPRs:ARRay:RFTX:EOFFset
Syntax
:MEASure:EGPRs:ARRay:RFTX:EOFFset <int1>
Parameters
int1 is an integer.
The minimum value for int1 is 0, the maximum value is 100. The default value for int1 is 0.
Description
Measures multiple times (set with the int1 parameter) the Origin Offset. The origin offset indicates the accuracy of
the i/Q modulators DC setup; it is usually an undesired leakage produced due to a DC offset in the phones I/Q
modulator. It is measured in dBc. To read out the entire measurement results array, use the
:FETCh:EGPRs:RFTX:ENFTh command.
Query
The query form of this command returns a string, containing int1 floating point real numbers with the physical
dimension of dBc, representing the measurement results.
The single measurement results are separated by commas.
Example
:MEAS:EGPRs:ARR:RFTX:EOFFset 5
:FETC:EGPRs:RFTX:EOFFset?
The maximum error vector magnitude measurement is performed five times. The measurement results are stored
internally and read by the FETC command. An example of the string returned is: "4.33,5.53,1.97,3.41,2.79".
:MEASure:EGPRs:ARRay:RFTX:FREQuency
Syntax
:MEASure:EGPRs:ARRay:RFTX:FREQuency <int1>
Parameters
int1 is an integer.
The minimum value for int1 is 0, the maximum value is 100. The default value for int1 is 0.
Description
Measures multiple times (set with the int1 parameter) the frequency error. To read out the entire measurement
results array, use the :FETCh:EGPRs:RFTX:FREQ command.
Query
The query form of this command returns a string, containing int1 floating point real numbers with the physical
dimension of Hz, representing the measurement results.
The single measurement results are separated by commas.
Example
:MEAS:EGPRs:ARR:RFTX:FREQ 5
:FETC:EGPRs:RFTX:FREQ?
The frequency error measurement is performed five times. The measurement results are stored internally and read
by the FETC command. An example of the string returned is: "22.33,22.53,21.97,22.41,21.79".
