measure different waveforms. You need to select the window function according
to different waveforms and their characteristics. Please read the table below
carefully to make an appropriate option according to the input signal.
Window
Applications and Characteristics
Rectangle
These are 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. Signals other than these
types will show varying amounts of spectral leakage and scallop
loss, which can be corrected by selecting another type of window.
Hanning
These reduce leakage and improve amplitude accuracy. However,
frequency resolution is also reduced.
Hamming
These reduce leakage and improve amplitude accuracy. However,
frequency resolution is also reduced.
Flat Top
This window provides excellent amplitude accuracy with moderate
reduction of leakage, but with reduced frequency resolution.
Blackman
It reduces the leakage to a minimum, but with reduced frequency
resolution.
 Press the Auto set softkey to automatically set the appropriate parameters for
the FFT measurement.
 Press the Display softkey to select Split, Full Screen or Exclusive display
mode.
Split: the source channel and the FFT operation results are displayed separately.
The time domain and frequency domain signals are displayed clearly.
Full Screen: the source channel and the FFT operation results are displayed in
the same window to view the frequency spectrum more clearly and to perform
more precise measurements.
Exclusive: the waveforms of channels are disabled, only the FFT operation
results are displayed in the window to view the frequency spectrum more clearly
and to perform more precise measurements.
 Press the Mode softkey to select Normal, Max-Hold or Average. When you
select Average, it is necessary to set the average times.
5. Press the Vertical softkey to enter VERTICAL menu.

 Press the Scale softkey, and then turn the Universal Knob to select the desired
vertical FFT scale
 Press the Ref Level softkey, and then turn the Universal Knob to select the
desired vertical FFT offset.
 Press the Unit softkey to select the unit of vertical axis. The units of the vertical
