40. Check for timing uniformity of DUT pixel matrix
###REMEMBER TO FIRST CENTER THE DUT AT AN ANGLE 0 degrees (It was DUT X 47 mm in the afternoon afternoon)###
For -90V bias, Telescope: 200 V
lowest thl possible (700?)
Angle: 0 degrees
20 spills per position (~5 minutes per step)
Depending on beam spot size, scan complete DUT (e.g. 1 around each corner and 1 in middle for big spot size)

41. Check for timing uniformity of DUT pixel matrix
For -90V bias, Telescope: 200 V
lowest thl possible
same as 40, but now 1 continues measurement while moving the DUT
