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 (?)
