READ:CDMA:MEAS<i>:MEValuation:TRACe:PERRor:AVERage?
READ:CDMA:MEAS<i>:MEValuation:TRACe:PERRor:MAXimum?
Returns the values of the RMS phase error traces. The values cover a time interval of
500 μs and contain one value per chip. The results of the current, average and maxi-
mum traces can be retrieved.
Return values:
<Reliability>
<PhaseErr1> ...
<PhaseErr616>
Range:
-180 deg to 180 deg
Default unit: deg

IQ Constallation Results (Traces)
The following commands return the results in the I/Q constellation diagram.
FETCh:CDMA:MEAS<i>:MEValuation:TRACe:IQ:CURRent?
READ:CDMA:MEAS<i>:MEValuation:TRACe:IQ:CURRent?
Returns the results in the I/Q constellation diagram. Every fourth value corresponds to
a constellation point. The other values are located on the path between two constella-
tion points.
Return values:
<Reliability>
<I_1> <Q_1> ...
<I_10240>
<Q_10240>
10240 pairs of normalized I and Q amplitudes, four values per
symbol period
Range:
-2.0 to 2.0

CDP and CDE Results (Traces)
The following commands return the code domain power (CDP) and code domain error
(CDE) trace results of the multi evaluation measurement. Both CDP and CDE are only
applicable to signals with H-PSK modulation.
