How does one detect ultrasonic oscillations?


With an ultraoscilloscope, of course.Â* Actually, any oscilloscope worth
a hoot will display waveforms up to 500 kHz which, other than in
exceptional cases, is all you need to worry about. You can still find 50
year old Hewlett-Packard scopes for under $25, and you can learn a lot
about audio (and about oscilloscopes) with one.


Surely most of even the cheapest nastiest (but perfectly adequate)
scopes from the last 50 years do 10MHz ?
