Chapter 4 Waveform Creation System
Waveform Creation using Front Panel-Vertex Mode
Vertex Mode
With the vertex editing mode, waveforms are created by establishing two anchor points at selected
addresses, positioning a vertex in the active region between the two anchors and then connecting the
vertex to the anchors with two line segments. The vertex mode also permits waveform scaling and the
insertion of standard functions. Vertex editing is illustrated in page 4-10.
1) Press EDIT key.
2) Press VRTX softkey (F2).
3) Select Waveform Number using edit knob or keypad (press ENTER after using keypad).
Selecting Left and Right Anchor Points
1) Press ANCH softkey (F3).
2) Set left anchor ( AL ) X value using edit knob or keypad. Press ENTER if keypad is used.
3) Use double-arrow key to move right anchor ( AR ) to right side of LCD. Set right anchor X
value using edit knob, keypad or optional mouse.
4) Press OK (F3) to store anchors or CANC (F4) to cancel.
NOTE
The difference between the left and right anchors is limited to 8000
points or the waveform length, whichever is less.
Selecting Vertex Point
1) Press ADDV softkey (Fl).
2) Set vertex X and Y values using edit knob, keypad or optional mouse.
3) When the desired position is reached, press
OK (F3) and the two line segments will be
stored. Press CANC (F4) to cancel.
4) Continue adding anchors and vertices until the waveform is completed.
Scaling
Scaling allows any portion of a waveform designated by the left and right anchors to be scaled in
amplitude and offset.
1) Select anchors as in page 4-6.
2) Press
SCAL softkey (F2).
3) Set digital amplitude (DA) and digital offset (DO) values for selected portion of waveform
using edit knob or keypad. Observe changes on output oscilloscope. Use double-arrow key to
select active parameter.
4) Press OK (F3) to store the scaled waveform or CANC (F4) to cancel.
