Tomorrow I'll upgrade this module manually to A
M1638: A
M1639: B Due to B at first -20C test. ROC8 mean noise >200electrons. Second -20C and at +10C both are graded A
M1640: B All three FT are B due to several ROCs mean noise >200electrons |
Following procedure of regrading the first -20C test has been manually upgraded to B. The final grade is A since manual upgrade was not taken in to account. I do not know why. So, the module will be graded A. |
