Preliminary Technical Data
AC test results with decimated averaging are shown
here. The SNR indicator also represents the
dynamic range when no signal is present.
The results are displayed in this chart. Also, the cursor
(yellow) can be dragged it to a desired location where the
X-axis values and the Y-axis value will be displayed.
