Test Equipment / Re: Standardised Way To Test Oscilloscope Screen Update Rate
« Last post by EEVblog on Today at 06:26:10 am »I am thinking about the purpose of the refresh rate.
Perhaps the screen refresh rate is less important than the ability to display the waveform appropriately – so a waveform with a 'glitch' repeated at different rates could be used to test for this.
Yes, in theory the display refresh/update rate shouldn't matter if the scope is designed to or set up to capture the thing you are interested in. Persistance is one obvious way to do that for example.
But often you are just causally using you Mk1 eyeball probing around, in whcih case you don't want your fast waveform capture rate hindered by a slow display update rate.
