Detector
ADC No Missing Codes
This test checks the ADC unlinearity and the missing codes. The result is presented
as "True" or "False".
Detector Offset Test
Measures the offset voltage at the ADC input with no light falling on the detector,
e.g. monochromator shutter closed. The detector gain is stepped up from 1*1 to
1000*16 with the minimum, maximum, mean ADC signal and standard deviation re
-
corded for each gain setting, as shown in the table below. The detector temperature
is recorded together with the ADC data.
