I have a device which can be modeled with a resistor in parallel with a capacitor. Now I want to measure its resistance and capacitance as a function of voltage bias (from -2V to 2V) and frequency (from DC to 10kHz). Originally I was thinking of using a LCR meter such as hand held Agilent U1732C which can measure in 100Hz, 120Hz, 1kHz and 10kHz. But the problem is I am not sure how to apply a bias and measure with this equipment at the same time. On the other hand, I don't need very high precision. I think 5% precision should be okay. But more frequency points from DC to 10kHz will be helpful. So my question is:
How can I apply bias on the device and measure its C and R using Agilent U1732C? Can I do that?
If 1 doesn't work, can I do it with a not-so-complicated DIY kit rather than resorting to a high-end LCR meter?
