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 Magnitude Error (Peak Hold) is a floating point number (in percent) of the Peak magnitude error over
the entire measurement area.
10 Phase Error (Average) is a floating point number (in degree) of the average phase error over the entire
measurement area.
11 Phase Error (Peak Hold) is a floating point number (in degree) of the Peak phase error over the entire
measurement area.
12 I/Q Origin Offset (Average) is a floating point number (in dB) of the I and Q error (magnitude squared)
offset from the origin.
13 Frequency Error (Average) is a floating point number (in Hz) of the frequency error in the measured
signal.
14 Rho (Average) is a floating point number of Rho.
15 Quadrature Error (Average) is a floating point number (in degree) of the quadrature error in the
measured signal.
16 Gain Imbalance (Average) is a floating point number (in dB) of the gain imbalance in the measured
signal.
17 Peak Code Domain Error (Peak Hold) is a floating point number (in dB) of peak hold Peak Code
Domain Error (of all the code channels, including active and inactive, in average cycle) of the selected
timeslot.
18 Peak Code Domain Error - Code Length (Peak Hold) is the code length of peak hold Peak CDE (in
average cycle) of the selected timeslot.
19 Peak Code Domain Error - Code Index (Peak Hold) is the code index of peak hold Peak CDE (in
average cycle) of the selected timeslot.
