Have an old Techtronix scope. Trying to understand the sweep: Sec/Div.
I have it set to 20µ and the sine wave is two major divisions. Is the 20µS per major division or per the minor divisions? If minor - would that be 4000 Hz?
How would I calculate the Hz?
The frequency I'm trying to understand is supposed to be ultrasonic, so 4kHz would be WELL within normal human hearing range. It's GOT to be greater than 20kHz. A dog barking device that's supposed to distract the dog and stop them from barking. I want to know what frequency it's operating on.
