OWON HDS-N Series Handheld DSO & DMM

8-Advanced Function of Oscilloscope

This is a very good window for measuring
amplitude accuracy but less so for resolving
frequencies.
Use Hanning for measuring sine, periodic and
narrow band random noise. This window works on
transients or bursts where the signal levels before
and after the event are significantly different.

Hanning

This is the best window for measuring the
amplitude of frequencies but worst at resolving
frequencies.
Use Blackman-Harris for measuring predominantly
single frequency waveforms to look for higher
order harmonics.

Blackman

Fig 61, 62, 63, 64 show four kinds of window function referring to sine wave of 1KHz.
