Dear Friends
?
Recently, I am suffering from a shimming
failure in a Bruker AVII+ 400 spectrometer. I have checked the 90 degree¡¯s pulse
length of 2H, it extended to more than 9 ms. When I changed this board with
another one functioning properly in a Bruker AV 400 spectrometer, the 90 degree
pulse is 150 us. I am sure that shimming failure should be due to the 2H-TX
board. My problem is that I have replaced this board at the end of last year
costly, I have to do this again after less one year. This could be a serious
issue for me. I wonder if anyone share experience.
?
Best wishes
