Waveform Generator 20

• X Position — Sets the lower, windowed points grid's beginning (left side) time.
The maximum X Position value is the full grid's width minus the width of the
windowed points grid.
• Insert, Cut, Copy, Paste, Undo — Arbitrary waveform points editing
buttons.
• Interpolate — Specifies how lines are drawn between arbitrary waveform points.
When enabled, lines are drawn between points in the waveform editor. Voltage
levels change linearly between one point and the next.
When disabled, all line segments in the waveform editor are horizontal. The
voltage level of one point remains until the next point.
• Reset — Clears all the arbitrary waveform points.
• Selected Point X — Lets you enter an exact time value for a point.
• Selected Point Y — Lets you enter an exact voltage value for a point.
• Arbitrary waveform points table — Shows the X and Y values of the arbitrary
waveform points.
Selecting rows in this table is another way of selecting arbitrary waveform
points.
To add modulation to the waveform generator output
Modulation is where an original carrier signal is modified according to the
amplitude of a second modulating signal. The modulation type (AM or FM)
specifies how the carrier signal is modified.
To enable and set up modulation for the waveform generator output:
1 In the Waveform Generator dialog box, click Modulation... to open the
Modulation dialog box.
2 In the Modulation dialog box:
• Select Modulation to enable or disable modulated waveform generator
output.
You can save arbitrary waveforms to internal storage locations or to a USB storage device, and
you can recall them later. See "To save arbitrary waveforms" on page 267 and "To recall
arbitrary waveforms"
on page 271.
