我对校准不是很了解,看log是要做AFC,但是我有几个问题哈。
1. 为什么GPS校准,却把Generator的频率设成935MHz?
SOURce:GPRF:GEN:RFSettings:FREQuency 935.000000E+6;*OPC?
这一句,意思就是将从“D:\WaveForm_MTK\loopC_W1230.wv”调用的波形文件的工作频率打到935MHz,但是GPS的频率不是1575.42MHz吗?
2. 为什么GPS校准,却是用GSM的测试界面?
前面一大段都在配置GSM的Mevaluation界面,包括
CONFigure:GSM:MEAS:BAND G09;*OPC?  # 频段GSM900
CONFigure:GSM:MEAS:CHANnel 0;*OPC?  # 信道0
怎么看都不像是要校准GPS。。。

至于最后为什么会fail,看这一句
2017/08/30 17:39:18.316 [GPIB] READ:GSM:MEAS:MEValuation:MODulation:AVERage?
2017/08/30 17:39:18.356 [GPIB] 0: 3,INV,INV,INV,INV,INV,INV,INV,INV,INV,INV,INV,INV,INV
Reliability indicator = 3,overdriven了,表示输入的信号太高了 。
SOURce:GPRF:GEN:RFSettings:LEVel -60;*OPC?
0: CONFigure:GSM:MEAS:RFSettings:ENPower 52.000000
信号发生器打-60dBm,期望功率52dBm,为什么还会高,没弄明白。

我对校准不了解,看log是做AFC,但是为什么GPS校准却是用了GSM的Mevaluation界面。调用波形文件后Generator的频率设成935MHz,频段设成GSM900,信道为0,等等一堆配置。没弄明白什么原理。

期望功率设52dbm??
把meta的log发上来看下就知道了
