As you mentioned it would be best if you could send the waveform so I can understand your problem. You can do this in two ways either:
Press the Prt Scr button on your keyboard (this will take a snapshot of your desktop), if you go into microsoft word and paste the copied image and attach the document to your post.
or
When in PicoScope click on File->Save As ->
choose a file name and then choose the format, I would recommend either
Data Files (*.psd) or
JPEG Files (*.jpg)
Problem with glitches aka "SPIKE." has been solved.
Electro magnets used in solenoids and other components usually induce a spike as the power is removed, the older vehicle I was dealing with even produced a large spike at turn-on, which caused me to chase my tail for a while.
with the helpful suggestions of my fellow PICO users, the source of the spike has been determined, and verified.
