> Investigate noise situation of AIDA (no DSSSDs connected) > > Figs 1-6: Waves, Pulser Peaks + Widths *before* any changes > - aida16 very noisy ASICS 1&2, normal ASICS 3&4 > - back-side aidas (02,04,06,08) worse resolution than front-side > - high-frequency noise still noticeable in waveforms > > Figs 7-8: Remove pulser in (from NIM rack) only > - no noticable change > > Figs 9-10: Remove all pulser cables from adapter boards > - looks improved > > Figs 11-12: HV Braid->GND Jumpers removed > > Fig 13-14: All HV cables removed > - aida06, aida14 isn't updating > - very noticable improvement > > Fig 15-16: Intermediate HV cables re-added > - signal worse in FEE64s with HV cables > - aida09, aida01, aida10, aida13, aida05, aida14 don't have HV interconnect cables, look good > > Conclusion: We see noticeable improvements removing the interconnect cables between FEE64s. > > Pulser widths now: > - aida14 (-ve amplitude) = 13.5 channels > - aida08 (+ve amplitude) = 40 channels (?)
