Analog Oscilloscope
How do you determine what MHZ you need for an Oscilloscope?
I want to purchase a scope for "home bench" use to do experiments, learn etc. I may also want to learn to service some types of electronic devices over time.
I see scopes statring at low frequencies upward. I need to stay less than $500 if I can.
I assume a 60 mhz analog scope will show within specs at that frequency but will also so even higher with some loss of accuracy.
I would appreciate answers in as much practical language as possible. I am not an engineer but I have functional knowledge.
you mean 50 MHz? 50 mHz is 0.05 Hz
No, it would have a pretty sharp cutoff at that frequency, you couldn't use it above perhaps 55-60 MHz. And I expect the accuracy to be reduced at 40-50 MHz, look at the detailed specs for the scope for exact numbers.
I suspect 10 MHz would be OK for you, unless you are getting into FM and TV frequencies.
