Entry  Fri May 7 01:49:03 2021, Rui-Jiu Chen, DAQ, Comparison of I_Raw/Q_Raw between different reference level  20210501_NTCAPPreparation.png
This is a comparison of I_Raw/Q_Raw between different reference level. The range of NTCAP ADC is only 2^15 bit. So signals (I_Raw and Q_Raw) should 
not be outside ADC range. It is clear that there is not point outside the ADC range when using reference level -30dBm.

Entry  Sun May 9 20:34:47 2021, Rui-Jiu Chen, Analysis, Comparison of frequency spectrum between 72Ge and other isotope 6x
This some preliminary analysis results by using  NTCAP data.   The IQ rate of NTCAP is 20 MSamples/seconds. I analyzed data files recorded from May 7 
17:39 to May 8 2:20.  The frequency of 72Ge is bended by 4kHz at the beginning of some injections.  In order to check whether this frequency bending is
