what is the time base set to ? horz, , I want to know the PRT, pulse repetition time. CKP.
due to the blooming of the trace (camera) I can not see if the blooming in a high frequency component there, as in NOISE.
if the blooming is real then set the input to AC mode and shorten the (higher freq) the horz. knob. dial faster sweep speed, see if there is some noise there.
also race the engine rpm so i can see the PRT go shorter.(time) and see if the 4v-p--p rises.
