The goal of this test is to determine the amount of noise that the synthesizer prouduces. After the noise is calculated, it is possible to find what the difference in plate gaps can be such that the noise of the synthesizer does not cover up the movement on a nanometer scale. The following is a schematic of the circuit set up for this test.
See calculation of power variation (noise) of synthesizer
See calculation of x, the acceptable offset distance of the plates versus noise of synthesizer
