Test with different sampling clocks ----------------------------------- Single events with zoom in time samples: mcm0-all-evtE--clkN-sS-zoomN.pdf OBS s3 for clk2 do not exist, instead s1 and s2. Single events full time sweep: mcm0-all-evtE-0-sS-clkN.pdf evt number E.

Peaks are searched for. Peaks is found if the width of ADC samples >= 200 is more than 1 (to avoid short spikes at softthreshold). For clk0 one expect 12 peaks per event. For clk1 one expects 12 peaks per event. For clk2 one expects 12 peaks per event. for clk3 one expects 5 peaks per event. Histograms plots: mcm13-2414-clkC-ped0-thr0-g0-s0-p1-s3-1-200-test-pulse.pdf plot 1-8: distribution of ADC values > 200. plot 9-16: MAX ADC value for all peaks found. plot 17-24: time sample of the peak max values. plot 25-32: number of time samples between peaks. expect: clk0: 60 clk1: 30 clk2: 15 clk3: 120 plot 33-40: width in time samples of all peaks. width should increase with the clock speed. csvfiles: mcm13-2414-clkC-ped0-thr0-g0-s0-p1-s3.csv Average and rms values of above plots. Comments: clk3 have some spikes in plot 1-8 for specific ADC values. clk0,1,3 have channel:chip7 chan10 with low peak values, capacitor has bad connection? clk2 not well analyzed since it has corrupt data, channels missing in many events.
