How to measure the value of a capacitor with an oscilloscope

In this video we demonstrate how to measure the value of a capacitor using an arbitrary waveform generator and an oscilloscope. In order to do this you will will need to be able to generate a square wave pulse between 100Hz & about 1KHz. Also your 'scope will have to be able to display both voltage and time cursors at once.
We will measure the time it takes to charge the capacitor to 63.2% of it's value (en.wikipedia.org/wiki/E_(mathematical_constant)) that number in either micro or nano seconds(delta X) will be the value of the capacitor in pF, nF,or uF.
If you would like more information on the theory behind this, Mike Lorton has an excellent video on the topic(youtube.com/watch?v=VylC8JFoiBo)\
