Cheap Relative Compression Test not Hantek

Trying out the new 35 dollar FNIRSI-138 Pro oscilloscope on the 4runner doing a relative compression test. This was even cheaper if you order without the 1x and 10x probe. I've been playing with it and its a pretty neat little scope. Perfect for those little things you want to check and its even battery powered. Not trying to sell it, just thought it was a cool option for those not wanting to spend over a 100 on a Hantek or 1,000's on a Picoscope.

Yes its only 1 channel. but hey, its also only 35 bucks :-)
