I am just looking for a general scope for use in projects in electronic/mechanical/control/mechatronic engineering at university level. Possible uses include checking the response of filter and sensor circuits, checking the outputs of motor controllers to see what signals are sent to the motors, checking if the receiver of a remote controller is receiving the same signals as signals sent from the sender, measuring the power consumption and current of the motors, etc.
I just out a few labs in several universities. It seems that 300MHz is the popular bandwidth. The ability to save the data either via a memory card inserted into the scope or via connection to a PC is important as I need to do post-processing to analyze the data and for plotting for reports.
Is it better to get 300MHz just in case? After hacking, what is the max bandwidth for the Rigol DZ1054Z?
Do the other two scopes have problem with discontinuity like the one described at 5:53 in the video?
