Hello Everyone,

I am using the Keithley 590CV for capacitance-voltage measurements on my
MEMS sensor which actuates when a voltage is applied. I have been getting
some odd results, and the Keithley 590CV has not been calibrated in a long
time and may not be working properly. Does anyone know of a product that I
could purchase and test with a known C-V curve? Perhaps an accelerometer? I
would prefer that i could use it on a probe station, and the capacitance
change should be at least 10fF.

Thanks,
Andrew O'Grady
