Source can be any channel, but not another math trace.
Select math operator +, -, x, or FFT.
If FFT is selected, select a window type:
Rectangular -- Normally used when the signal is transient
(completely contained in the time-domain window) or
known to have a fundamental frequency component that is
an integer multiple of the fundamental frequency of the
window.
known to have a fundamental frequency component that is
an integer multiple of the fundamental frequency of the
window.
VonHann -- Reduces leakage and improves amplitude
accuracy. However, frequency resolution is also reduced.
Flat Top -- Provides excellent amplitude accuracy with
moderate reduction of leakage, but with reduced frequency
resolution.
