recently i bought a Hitachi v-550B 50MHZ scope of eBay. it powers up and there is a trace. when i feed the 1khz square wave from the scope to channel one if the volt/div is below 0.1mv i get overshoot and undershoot in the square wave, if its above 0.1 i get kinda of a square wave. picture 1 and 2
now channel two is kinda mad to, i get whats is in picture 3, regardless of the voltage division
i have checked the 1khz wave with my rigol scope and it is a perfect square wave.
does anyone know what could be the problem?
thanks
