Differential Conductance Lock-in method...Help!!!!

[​IMG]



This is the technique overview to obtain differential conductance. Now for the question:

I am using the reference ac signal from the lock in amplifier and dc from a dc source meter; how do I combine the ac and dc together???
Is a coupling capacitor the answer??

Please help!!!

    If you combine AC and DC together there is possibility your current and volatge might lag or lead and also frequency plays an important factor....u can use a coupling capacitor...i have to check out if there are any other methods!!!
