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 (0.0 = pass, 1.0 = fail)

2 Peak EVM pass/fail result (0.0 = pass, 1.0 = fail)

3 Frequency Error pass/fail result (0.0 = pass, 1.0 = fail)

4 Rho pass/fail result (0.0 = pass, 1.0 = fail)

5 Peak Code Domain Error pass/fail result (0.0 = pass, 1.0 = fail)

6 RMS EVM (Average) is a floating point number (in percent) of EVM over the

entire measurement area

7 Peak EVM (Peak Hold) is a floating point number (in percent) of the Peak EVM

in the entire measurement area.

8 Magnitude Error (Average) is a floating point number (in percent) of the average

magnitude error over the entire measurement area.

9 Phase Error (Average) is a floating point number (in degree) of the average

phase error over the entire measurement area.

10 I/Q Origin Offset (Average) is a floating point number (in dB) of the I and Q

error (magnitude squared) offset from the origin.

11 Frequency Error (Average) is a floating point number (in Hz) of the frequency

error in the measured signal.

12 Rho (Average) is a floating point number of Rho.

13 Peak Code Domain Error (Peak Hold) is a floating point number (in dB) of the

Peak Code Domain Error relative to the mean reference power.

14 Peak Code Domain Error Channel Number (Peak Hold) is the channel number

in which the peak code domain error is detected.

15 Number of active channels.

16 Time Offset (Average) is a floating point number (in chips) of the pilot phase

timing from the acquisition trigger point.
