Both of the systems you mention (the start signal generation and the stop
signal) are external to the tests performed with the WFD CLI last week by
Ioannis (and Roberto?). Normally when you use the CLI, the acquisition is
stopped and you use the buttons on the WFD Signal Fanouts, not the stop
and start signals that were fixed. Unless the WFD on SM3 was restarting
during the CLI tests and no-one noticed (the lights on the WFD would have
been all green), there was something else causing the digitization of
bogus data.
I still believe the problem could be now "fixed," but we should keep an
eye on it.
