Chapter 18 Function/Arbitrary Waveform Generator (Option)
Set the initial number of points
⚫
The initial number of points indicates the number of editable points. By default,
the number of editable points of arbitrary waveforms created can be preset to 2.
Point 1 is fixed at 0 s and Point 2 is fixed at the middle of the period. Press Init
Points, then rotate the multifunction knob
keypad to set the number of editable points for the arbitrary waveform. The
maximum number of editable points supported by the system is 16,384 (16
kpts).
Linear interpolation
⚫
Press Linear Interp to enable or disable the linear interpolation between the
defined points of the waveform.
ON: the waveform editor connects two defined points using a straight line.
➢
OFF: the waveform editor will keep a constant voltage level between two
➢
points and create a ladder-like waveform.
Edit points
⚫
Press Edit Points to enter the point editing menu. You can specify the voltage
value for each waveform point to define the waveforms.
Current Point
➢
Press PointX, then rotate the multifunction knob
numeric keypad to select the points to be edited. The available range is
from 1 to the number of initial points.
Voltage
➢
Press Voltage, then rotate the multifunction knob
numeric keypad to set the voltage value of the current point. Its available
range is from -2.5 V to +2.5 V.
Insert
➢
Press Insert to insert a new editable point between the current editing
point and the next editing point. The number of initial points adds 1
automatically. You can press Insert continuously to increase the editable
points gradually.
Delete
➢
Press Delete to delete the current point from the waveform, and connect
the remaining points with the current interpolation method.
Note:
The 1
Zoom
➢
Press Zoom continuously to enable or disable the zoom function of
horizontal time base.
Apply
➢
Press Apply to apply the current settings for the currently edited arbitrary
waveforms and output the edited waveforms.
Save the arbitrary waveform
⚫
Press Save to enter the file saving interface. Please refer to descriptions in
"Store and Load" to save the currently edited waveform file to the internal or
