FT of M1542, M1557, M1630, M1649 only at +10C |
|
|
M1542 has grade C for relative gain width. Was tested with early versions of test SW with trim VCal=40 and not yet optimized PH optimization/calibration.
Other modules have grade C only at +10C. This time CtrlReg=17 instead of 9 is used/
M1542: Grade B due to 61 pixels failed Threshold criteria (trimming)
M1557: Grade B due to mean noise and NOT any more like in FT 214 pixels failed Threshold criteria
M1630: Grade B due to mean noise and NOT any more like in FT 3883 pixels in ROC1 failed Gain criteria
M1649: Grade B due to mean noise only in one ROC and NOT any more like in FT 270 pixels failed Threshold criteria |
