ASIC settings - attachments 1-4 
Slow comparator 0x80
N.B. new ASIC settings software in use

Adaptor PCB *without* jumpers

FEE64 temperatures OK - attachment 5

WR timestamp OK - attachment 6


aida01
Rate, 1*L and 1*W spectra OK - attachments 7-9

FEE64 temperatures OK - attachment 10

aida02
Rate, 1*L and 1*W spectra OK - attachments 11-13

aida03
Rate, 1*L and 1*W spectra OK - attachments 14-17

No ADC spectra asic #4 *but* Rate, HitRate, 4*W spectra all indicate asic #4 working OK - contact issue?

aida04
Rate, 1*L and 1*W spectra OK - attachments 18-23

Bad ADC spectra asic #2 *but* Rate, HitRate, 2*W spectra all indicate asic #2 working OK - contact issue?

Following disassembly and re-assembly

aida03 *.*.L 15.0,15.9,15.0,15.4 ch FWHM ( ADC data all channels, similar peak widths all channels )
*.*.W spectra OK
Rate, HitRate spectra OK

aida04 no change - 2.*.L spectra still bad
