Input overload

A useful feature would be a "LED" on the Cleverscope Control Panel (and possibly on graph screens as well) that illuminates when the ADC reaches full scale. I have been caught a couple of times now by overloaded input. Thanks, Bruce.

Hi Bruce,
an overloaded ADC input will be manifested by the signal being off the screen. Recovery time is supposed to be one sample. How else is this a problem to you?

cheers, Bart

hi Bart,

I am not quite sure of the specifics, but we were debugging some circuitry directly connected to mains i.e. about 700V p-p. We were using a 10x probe. The signal was all onscreen and was ""flat topped"". It took us a while to realise our circuit was actually OK but the screen was not indicating actual circuit conditions. Purchasing a 100x probe sorted it, but I do feel that some indication of ""overload"" would be sensible. Maybe the input amp before the ADC was clipping - I really don't know, but I am sure you would. Thanks, Bruce.
