Changing the Averaging Value
Changing the Averaging Value
The averaging value is where noise can be averaged out from a waveform,
pulse or pattern. The number of averages can be between 1 and 64, and
infinite.
In the figure below, the 127-bit pattern is averaged and the noise is
removed. Note that this works for patterns, pulses and waveforms, not
eye-diagrams, since it does not represent a continuous curve. The number
of averages can be set from 1 to 64 and infinite.
The averaging function uses the pixel information to calculate the average.
This means that a higher resolution in pixels/ps is achieved in a zoomed
window compared to the default window.
