How to measure RCDE with MXA N9020

Hi all, 

How can you measure Relative Code Domain Error for BTS measurements using MXA N9020A? 

It is disabled in the Mod Accuracy tab for BTS mode (perhaps to do with the fact in BTS/DL mode the DPDCH and DPCCH are time-multiplexed while in MS/UL mode it is I/Q separation).  

I am thinking of calculating the RCDE using the equation from 25.141 Appendix E. 

Typical values being reported is around -8.9dB where the limit is -20. 

Please advise if my understanding is correct or not and any improved measurement method. Any links for any related documents will also be helpful. 

Many Thanks.
