nnaida14 - input -, shaping time 2us - attachment 4
Note - nnaida11 1.12.L pulser peak width ~45 ch FWHM (integrate)
Test conducted yesterday and today suggest that it is the grounding and/or
the AIDA adaptor PCB that is significant - *not* the particular LH coupler
+ 2x 34-way ribbon cable + 3M 1245 Cu foil screen assembly or FEE64 polarity
Current AIDA adaptor PCB configuration
nnaida11 rev C, LK1 fitted
nnaida14 rev B, no links fitted
15.37 Add LK1 to nnaida14 AIDA adaptor PCB - no significant change
nnaida11 - input +, shaping time 2us - attachment 5
