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.
5. Press the Center softkey, and then turn the Universal Knob to select the desired
center frequency.
6. Press the
Hz/div
softkey, and then turn the
Universal Knob
to select the desired
resolution frequency.
7. Press the Scale softkey, and then turn the Universal Knob to select the desired
vertical FFT scale.
8. Press the Ref Level softkey, and then turn the Universal Knob to select the desired
vertical FFT offset.
9. Press the Unit/Load softkey to enter Unit/Load menu. Press Unit softkey to select the
unit of vertical axis. The units of the vertical axis can be dBVrms, dBm or Vrms which
use a logarithmic scale or a linear scale to display vertical amplitude respectively. If
you need to display the FFT frequency spectrum in a relatively larger dynamic range,
dBVrms is recommended. Press
Ext Load softkey, and then turn the Universal Knob
to select the external load value.
10. Press the Mode 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 displayed waveforms of all channels are disabled, only the FFT
operation results are displayed in the window. This isolated view allows you to
view the frequency spectrum more clearly and to perform more precise
measurements.
