1. Pixel
Control the presentation of the “superposition waveform” in the top panel.
PIXEL = A-B
The waveform shown in the top panel will be calculated by subtracting pulse amplitudes of the B-waveform from the corresponding pulse amplitudes of the A-waveform.
This is the default choice.
PIXEL = B-A
The waveform shown in the top panel will be calculated by subtracting pulse amplitudes of the A- waveform from the corresponding pulse amplitudes of the B-waveform.
2. Mark sequences…
Draw a thin vertical line every N pulses in the superposition display. You will be prompted for the value of N. Use it, for example, to mark line addressing times. Choose this menu item again to remove the marks.
Alt–click to select entire sequence of pulses between the marks.
3. Zoom in
Zoom buttons above time units
Alter the scale of the waveform display. The current zoom ratio is shown at the bottom of the window.
4. Zoom 1:1
Center button above time units.
Restore the situation where the pulse width expressed in “units” corresponds directly to the same number of pixels on the screen.
5. Zoom out
Zoom buttons above time units
Alter the scale of the waveform display. The current zoom ratio is shown at the bottom of the window.
6. Set grid
Hierarchical menu. Chose the size of the support grid for drawing pulse amplitudes. It automatically calls SNAP TO GRID and, if the grid is not too dense to display, SHOW GRID.
SET GRID » EQUAL STEPS…
ctrl–Y
You will be prompted for the step size. The positive and negative values are symmetrical by default.
SET GRID » SAME AS OTHER WAVEFORM
Make the grid in the active waveform exactly the same as in the non active waveform.
7. Snap to grid
The value of a currently edited pulse amplitude is adjusted to the nearest grid level. The grid does not have to be visible.
8. Show grid
Make the grid visible. Choose this menu item again to hide the grid.
