Special care must be taken and the proper equipment must be used when testing the Fresno design. The key
to testing any high-accuracy design is to use sources and measurement equipment that are of higher accuracy
than the design under test. A low distortion signal source is absolutely required in order to duplicate the
presented results. The input signal was generated using the Audio Precision SYS-2722. The FFTs were
created using the FFT control in SignalLab from Mitov Software.
AC and DC performance for on-board isolated power is shown in Figure 4 and Figure 5. AC and DC
performance for external power is shown in Figure 6 and Figure 7.
