Procedure for Setting Timing of Switches
1. Draw desired switching diagram for
your application.
2. Select cycle time for your application.
It must be greater than 50μs and less
than 500ms.
3. Calculate the trigger frequency,
f
TRIGGER
= 1/cycle time.
4. Apply power (±15, +5, ground) and the trigger
signal to the DEM-ACF2101BP board.
5. Select desired pulse width. It must be greater
than 6ns and less th an 36μs.
6. Adjust desired pulse width by setting SW1,
Row 2 to Column D and Row 2 to Column E.
Look at Select signal on a scope and adjust
signal width with RV
1
.
7. Set the Rows of SW1 to match desired columns
to match switching diagram.
8. NOTE: The rise edge of the Reset switch should
not coincide with the falling edge of the Hold switch.
If it does, there is a chance that data wll be lost.
