Hello
I have a project in which I need to detect the microbubble response to ultrasound excitation. The waves which are to be generated and therefore measured will range from 1MHz-20MHz.
I have an old oscilloscope that only has a 1M ohm 20pF input impedance, and I am aware that high frequency signals require a 50 ohm input impedance.
Is there any way I can use this scope for my project by using a probe or something to bypass this impedance problem? Also, any basic info on how the input impedance of the scope affects the circuit/signal would be appreciated.
Thank You
