Return values:
<Reliability>
<EVM_1> ...
<EVM_n>
n EVM values, one per subcarrier
For not allocated subcarriers NCAP is returned.
Range:

Magnitude Error Results (Traces)
The following commands return the magnitude error vs. SC-FDMA symbol results of
the multi evaluation measurement.
FETCh:LTE:MEAS<i>:MEValuation:MERRor:CURRent?
FETCh:LTE:MEAS<i>:MEValuation:MERRor:AVERage?
FETCh:LTE:MEAS<i>:MEValuation:MERRor:MAXimum?
READ:LTE:MEAS<i>:MEValuation:MERRor:CURRent?
READ:LTE:MEAS<i>:MEValuation:MERRor:AVERage?
READ:LTE:MEAS<i>:MEValuation:MERRor:MAXimum?
Returns the values of the magnitude error bar graphs for the SC-FDMA symbols in the
measured slot. The results of the current, average and maximum bar graphs can be
retrieved.
