Averaging by Each Measurement Point (Point Averaging)

With point averaging, each measurement point is measured the number of times designated
by the user, and the average measured vector quantity sets the value for that point.
Accordingly, sweep time becomes longer in proportion to an increased number of times set
for averaging. Point averaging is performed according to Equation 3-2.

M = Calculation result of point averaging at the measurement point (vector quantity).

F = Point averaging n-times.
Set point averaging by following the procedure below.
Procedure
Step 1. Right-click to open the shortcut menu and click
Step 2. Enter the number of times for point averaging with the numeric entry dialog box that
appears by right-clicking inside the
block keys on the front panel.
For example, to set the point averaging number of times to 8, click
numeric entry dialog box (or press
keys on the front panel).
