Re: What frequency limit I should plan for when choosing oscilloscope for TV repair?
Here's what I see on the scope from the output of the voltage sense circuit. This is not the one in the variac , but the identical circuit. The input voltage is 100V and Ohms law says the output should be 33mv, so it's pretty close, but that 1.3mv that it's off amounts to the meter being over 3v off. The one in the variac is probably more accurate, because I've upgraded to all 0.1% resistors.
