and their characteristics. Please read the table below carefully to make
an appropriate option according to the input signal.

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 Screen, Full Screen or Exclusive
display mode.
Split Screen: Time domain waveform and frequency domain waveform
are displayed separately. The time domain waveform is on the upper
half screen, while the frequency domain waveform is located within the
lower half of the display. In Split mode, if Zoom is enabled, the zoom
waveform and the frequency domain waveform are displayed on the
lower half screen together.
Full Screen: Time-domain waveform and frequency-domain waveform
are displayed together.
Exclusive: Only the frequency-domain waveform is displayed.
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 vertical axis
units can be dBVrms, dBm, Vrms or dBArms, Arms, which use a
