TOOLTOP ET120MC2 Oscilloscope Review

Let's test a pocket oscilloscope. These small devices have improved steadily over the years and are now quite useful. But you need to know what they are best suited for. I give this some challenging tasks including trying to monitor the RF envelope from a Sanyo VTC5000 Beta (Betamax) video recorder, and compare it against some other oscilloscopes.
