Notice:
The recalled waveform number increases no matter what button that you
press,
or
. If it reaches the biggest number, it will return to the smallest in circles.
(8) Spectrum Analysis
Once a waveform is measured, you may analyze the frequency spectrum at once
by press
〖
W.Spect
〗
.
If you just
recall a waveform
with
〖
W.Recall
〗
and then press
〖
W.Spect
〗
,
you will see the spectrum of the stores waveform.
The screen of spectrum displays as the following graph. The original location of
the cursor is in the place of zero frequency. Press
or
to move the cursor. The
frequency and the amplitude of the cursor location is displayed at the right of the
screen.
