WAVEFORM MATH
Standard math functions comprise addition, subtraction, multiplication, and FFT. The
“Math” menu is accessed by pressing the MATH front panel button in the VERTICAL
control group.
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.
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.
