Hi Jolyon,

Any low impedance step function circuit will work.  There is a concern that 
you need enough voltage to get good signals on the test equipment.  I used 
a 2500 volt step for Paul's Qvar experiments:

A pretty elaborate machine but it was to get good signal strengths and do 
long term timing functions.
