 Fri May 7 01:49:03 2021, Rui-Jiu Chen, DAQ, Comparison of I_Raw/Q_Raw between different reference level 
|
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. |

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
due to isomer or unstable magnetic field. I compare the 72Ge with other isotopes. The similar bending was observed for other isotope in each
corresponding injections. It seems that bend is due to unstable magnetic field. |
