Adjust the phase difference at the phase detector as prompted by
the phase noise software.

The system will measure the positive and negative peak voltage of
the phase detector using an internal voltmeter. The quadrature
meter digital display can be used to find the peak. The phase may
be adjusted either by varying the frequency of the source or by
adjusting a variable phase shifter or line stretcher.
