Smoothing sets the number of points before and after a graphed data point that are averaged for the display. When 0 is set, it means
that the raw data is displayed. If 3 is selected, 3 points before the measurement and 3 points after the measurement are averaged and
the result is plotted on the graphic display.
Averaging is the number of sequential traces that are averaged for each trace. Check the
Auto
box (Automatic Gain & Slope Offset) to
have the Gain and Slope Offset set automatically based on the Location Limits. The CX380C will compare the limits set for the current
Location to the limits set for the location of the Reference File and then offset the test results by the appropriate Gain and Slope Offset.
