出问题了

一个WCDMA的网卡项目,暗室TRP居然25,这个数值不正常,测传导作对比,数值在20左右,问题来了,高出的5DB是怎么回事?

给ETS发了邮件,很快收到回复:

I have saw the data from you, I have some questions and suggestions about it
What are about your TRP test using the Goldphone, is it stable?
If the Goldern Phone test is stable, please according to  the PRM files to change the setup of the 8960 and have a try.
If the Golden Phone test is not stable, please check the SA and the switches. Maybe the times of the TEST was too many, the swtiches was wastage.
Two ways: 1. Checking the Range loss whether is stable after constandly change the switches mannually.
           2, Using two cables, one was connect the Port1 of the ENA with the middle port of one switch, another cable is connect with the NC or the NO, constandly change the switch mannualy, and see the S21 is whther stable.
          Any results please tell me.

很不幸,根本没有WCDMA的金机。,只有手工切换switch通过测rangeloss进而确定是不是switch的问题,今天是没时间了,看看明天有空的话再搞吧!
