QPSK EVM results
Index Result Parameter
0 Overall Pass/Fail Result shows the mask test result (0.0 = pass, 1.0 = fail, -1.0:
Not tested)
1 RMS EVM pass/fail result (1.0 = fail, 0.0 = pass) Returns the result of whether
the RMS EVM passed the limit set in the measurement setup.
2 Peak EVM pass/fail result (1.0 = fail, 0.0 = pass) Returns the result of whether
the Peak EVM passed the limit set in the measurement setup.
3 Magnitude Error pass/fail result (1.0 = fail, 0.0 = pass) Returns the result of
whether the Magnitude Error passed the limit set in the measurement setup.
4 Phase Error pass/fail result (1.0 = fail, 0.0 = pass) Returns the result of whether
the Phase Error passed the limit set in the measurement setup.
5 Frequency Error pass/fail result (1.0 = fail, 0.0 = pass) Returns the result of
whether the Freq Error passed the limit set in the measurement setup.
6 IQ Original Offset pass/fail result (1.0 = fail, 0.0 = pass) Returns the result of
whether the IQ Original Offset passed the limit set in the measurement setup.
7 RMS EVM (Average) is a floating point number (in percent) of EVM over the
entire measurement interval.
8 RMS EVM maximum is the maximum RMS EVM over the average group. If
averaging is off, then it returns result for the measurement interval.
9 Peak EVM is a floating point number (in percent) of the Peak EVM in the
measurement interval.
10 Peak EVM maximum is the maximum Peak EVM over the average group. If
averaging is off, then it returns result for the measurement interval.
11 Magnitude Error is a floating point number (in percent) of averaged magnitude
error over the entire measurement interval.
12 Magnitude Error maximum is a floating point number over the average group. If
averaging is off, then it returns result for the measurement interval.
13 Phase Error is a floating point number (in degrees) of the averaged phase error
over the entire measurement interval.
14 Phase Error maximum is the maximum Phase Error over the average group. If
averaging is off, then it returns result for the measurement interval.
15 Frequency Error is a floating point number (in Hz) of the frequency error in the
measured signal.
16 Frequency Error maximum is the maximum frequency error over the average
group. If averaging is off, then it returns result for the measurement interval.
17 I/Q Origin Offset is a floating point number (in dB) of the I and Q error
(magnitude squared) offset from the origin.
