GSM PCS频段低功率级别PVT fail,请高手指点

具体见图形，调试PVT Profile是没有用的，应该是要调整时序 请高手指点
就是图形最上面的那个拐点，我修改了PT2没有改善

你可以请你们PA的供应商的FAE帮你改。
这个很好改啊，小编你们公司没RF工程师吗?

发射的时序一共就那么几个，来回改改呗。

For DCS 1 800 and PCS 1 900 MS:
-4 dBc for power control level 11;
-2 dBc for power control level 12;
-1 dBc for power control levels 13, 14 and 15.
For DCS 1 800 and PCS 1 900 MS:
-30 dBc or -20 dBm, whichever is the higher.
兄弟，你的测试模板用错了。协议规定不是非要到-30dbc的！也可以是-20dBm

解决了吗?刚也碰到这个问题，把校准文件里DCS频段的DC OFFSET设为0试一下。
