Setting Window Value Correctly - Saluki S3601 Series User Manual

Effects when using window wave filter is shown below:
The Analyzer performs window filtering to frequency domain Measure data and has following effects on time domain Measure of the
measured piece:
In impulse transformation mode, it affects pulse width and sidelobe level, changing resolution and dynamic range of Measure.

In low-pass step transformation mode, it can mitigate overshoot and ringing.


8.3.2. Setting Window Value Correctly

When performing time domain Measure, proper window value must be selected according to response type of the measured piece:
Response of the measured piece with identical amplitude: small window is selected to obtain narrow pulse width to improve

resolution of time domain Measure.
Response of the measured piece with different amplitudes: large window is selected to obtain low sidelobe level to improve

dynamic range of time domain Measure.
