4.6 Using Arbitrary Waveforms
a) Outputting an arbitrary waveform
Select [ARB] (arbitrary waveform) in the
[Fctn] field and then press the
ENTER key.
The currently set arbitrary waveform is
output.
Like for other waveforms, the polarity and
amplitude range of the waveform can also
be changed.
b) Changing the waveform of an arbitrary waveform
1.
When the waveform is set to [ARB]
(arbitrary waveform), the [Select] button is
displayed to the right of the polarity/
amplitude range icon.
When this button is selected, the currently
selected arbitrary waveform name is
displayed.
Press the
ENTER button to display
the screen for selecting currently saved
arbitrary waveforms.
2.
Arbitrary waveform selection and name change can be done on the arbitrary waveform
selection screen. “Oscillator > ARB Select” is displayed in the top left part of the arbitrary
waveform selection screen.
Set the number of the waveform in the [ARB No.] field. The waveform can be selected
from waveform No. 0 saved in volatile editing memory and the waveforms No. 1 to No.
128 saved in non-volatile memory. The outline of the selected waveform can be checked
with the graph display. The [Type] field shows the arbitrary waveform data format, and the
[Size] field shows the memory size used for saving data.
The changes are not reflected to the output waveform until applied by pressing the [OK]
soft key (the operation differs from that for parameter-variable waveforms).
Arbitrary waveforms cannot be created on this screen. For how to create arbitrary
waveforms, data fomat, and memory size,
) “2. CREATING ARBITRARY WAVEFORMS”
in the Application Instruction Manual.
The name changing method is the same as for the setting memory. Names of up to 20
characters can be set.
