Some of my guys want to build a bunch of special test sets to do
production testing... of a general-purpose test system! It can test
itself!

Coincidentally, I\'m just finishing up an app note on how to test
photoreceivers, based on a couple of our internal test gizmos that
turned into products.

Right. Why build some complicated custom test set, when you could
build something that can be sold as a product?

The other concept here is is \"sunk cost.\"

Are you claiming the concept of self-test an original idea, of wide practical use, that fills a need in demand by industry, no description of which has ever appeared in the open literature?

There could be cases where a dedicated test set might be better if it used
different technology. That way it might be better able to catch systematic
errors that cancel out when one instance of something is used to test another
instance of itself.

You could always equip your automated test system with an
on-board automated gremlin.

I think you mean that a working test system can be used to
test another system. Well . . . . duh; but only if it\'s
designed and programmed to do so.

Self check and self calibration are pretty common, but
can also be another mode of failure.

Stuff that just goes gets my vote.
