7.4.10 Averaging/Smoothing and Resolution Bandwidth
Averaging [time average] and smoothing [moving average] are provided as the function which
statistically reduces random errors that cannot be reproduced. (Refer to (1) and (2).)
Narrow resolution bandwidth will reduce noise component, thus decreasing random errors. How-
ever, the case will increase the sweeping time.
The Setting and the Explanation
Press the [AVG] to call the average menu. (Refer to section A.4.)
Average menu
{AVG STATE ON/OFF}
: Selects ON/OFF of averaging.
{AVG COUNT}
: Sets the number of times for averaging.
{AVG RESTART}
: Resets the averaging and restarts at the average time 1.
{GROUP DELAY APERTURE}: Sets the aperture for group delay measurement. The
aperture should be considered in the same manner as
the smoothing aperture.
{SMOOTHING ON/OFF}
: Selects ON/OFF of smoothing.
{SMOOTHING APERTURE} : Sets the smoothing aperture.
{TRACE 2ND/1ST}
: Selects between the 1st trace and the 2nd trace.
{IF RBW [ ]}
: Sets the resolution bandwidth. When "0" is entered, the
resolution bandwidth is automatically set [AUTO]
depending on the measurement frequency.
