short pulse, large variance of before and after signals.
● Blackman
：
The best range resolution, the worst frequency resolution, it can be used to measure the single
frequency signal, to find higher harmonics.
(2) Set Vertical Unit
Vertical units can be Vrms or dBVrms. Press F4 to select the desired unit. Vrms and dBVrms show the vertical
amplitude by means of logarithmic and linear. To display the FFT spectrum in a larger dynamic range, dBVrms can
be used.

During operation, when the source channel voltage value is greater than the corresponding channel trigger value,
the logic decision will be 1, otherwise it is 0. Waveform transform will be in binary operation. Four logical operations
examples are shown in the table below.
