关于GSM手机功率/时间模板fail
其实送去作CTA的机器最好在校准的基础上进一步优化一下射频参数,防止出现由于测试系统不同而出现的意外。
可我测量的结果的冗余度是很大的,而CTA的测试结果也不是超标而是Unable to measure ,我可有些摸不着头脑了
能把CTA的测试数据拿来吗?

Something must be wrong with synchronization of the burst, check your ramping mask performance in both amplitude and midamble synchronization mode in 8960.
If there is no problem, I am afraid there are some software or protocol incompatible.
There is another possibility that the 8922 met some trouble, I met similar troubles before on 8960.
tell them the result on your own instrument.maybe the 8960 or cmu needs calibration.(1 cal 1 day)
什么是8960的amplitude and midamble synchronization mode?
