Performing Averaging
When the measured trace does not appear smooth on the display, a smooth trace may be
obtained by performing point averaging or sweep averaging. Especially for the high Q (low
D) measurement, you should perform averaging. This section describes the procedure for
averaging by using the setup example of Figure 3-61, "(2) Frequency Characteristics of
|Z|-R-X," on page 84.
Averaging
Averaging includes point averaging and sweep averaging.
o Point averaging
Point averaging smooths the trace by repeating the measurement on each measurement
point until the averaging count is reached (Figure 3-67).
o Sweep averaging
Sweep averaging smooths the trace by repeating the sweep until the averaging count is
reached (Figure 3-67).
NOTE
Point averaging and sweep averaging can be performed at the same time.
