    I know how to meaurre voltage on CRO.
    I want 2 c charging of cap, which takes milliseconds. But how to record waveform on cro t analyse it later

    In the old days we had a camera attachment on the screen of a CRO. You would take a Polaroid photograph and analyze it later.

    If you just want to see the effect of the charge curve, feed a network made of a resistor and capacitor with a square wave. You will see both the charge and discharge curve as the square wave switches from high to low state. Resistor and cap in series with loose end of cap tied to common and loose end of resistor tied to square wave source.
