Attachments 1, 3, 5 & 7 *.L spectra log scale

Attachments 2, 4, 6 & 8 *.L spectra linear scale (expanded around pulser peak) 

Attachments 9-12 *.W spectra 20us FSR 

Observe 

2.13.L low amplitude
2.14.L & 3.3.L large number of counts and 'sinusoidal' continuum

... but ... the corresponding waveform spectra look OK

Zero'd all histograms to confirm observations - confirmed - see attachment 16
Pulser peak width spectrum 3.8.L 71 ch FWHM
