An unboxing anf first impression of the OWON 14bit XDS3202A Oscilloscope.
Note, this was shot as single take for the 2nd channel, but thought it might be better off here but with no EEVblog number. It is NOT a review. If you don't like unboxings and just bumbling around with the scope the first time and ranting then please don't watch it.

Dave explains, shows, and measures a potentially big trap with using high value ceramic capacitors.
Is your 10uF capacitor really 10uF in your circuit? You might be shocked!
Those humble X7R caps you think are a "stable" dielectric? think again...
Class II and above ceramic capacitors can vary their capacitance drastically with DC bias voltage level and also the applied AC voltage.
