Pulse Generator

[sinbad]

Anyone have a simple circuit for a pulse generator that will give 1.5ms nominal as used for servo testing? There may be some 555 or 7555 timer circuits that may fit the bill. Any help on this? I don't have any application books at this time.
Thanks,
Sinbad

If you do a search of this forum there are few threads on servo testers......from basic timer chpped ones, to pic based testers....... ;)

You could use the circuit I posted

but you can eliminate the 555 on the right, and all it's associated components up to and including the 1N4148. If you like, I'll redo the schematic and post it here.
