Reference Waveforms are saved waveforms to be selected for display. The reference
function will be available after saving the selected waveform to non-volatile memory.
Press M/R button to display the Reference waveform menu.
Select menu Enable->ON to enter reference function window. The reference function
window is displayed in Figure 2-15.
Features
Best frequency resolution and
worst magnitude resolution.This
is essentially the same as no
window.
Better frequency, poorer
magnitude accuracy than
Rectangular. Hamming has
slightly better frequency
resolution than Hanning.
Best magnitude, worst frequency
resolution.

Best for measuring
Transients or bursts, the signal
levels before and after the
event are nearly equal.Equal-
amplitude sine waves with fixed
frequencies. Broadband random
noise with a relatively slow
varying spectrum.
Sine, periodic, and narrow-band
random noise. Transients or
bursts where the signal levels
before and after the events are
significantly different.
Single frequency waveforms, to
Find higher order harmonics.
