Parallax oscope input impedance

Hello, Everybody
I want to make x10 probe for my Parallax oscope. I know that input impedance is standard 1M, but what capacitance does it have. I'll need it to add matching RC pair to the probe. I know that resulting characteristic time will be below the scope resolution anyways, but it still would be better to avoid unnecessary interference in digital circuits where sharp voltage steps are often.
Hope someone here has the answer to this question.
Thank you
Rita
