It was more if a hint to RPL to look up Keyswitch in their equipment rental catalogueWould be interesting to see this, yes. So if any hobbyist on here has spent more on their scope than their car, perhaps you could share some shots...Has anybody put a very high speed scope on this effect ? I wonder if rather than it entering some latch-up state, it is in fact 'honking' at whatever the max frequency of the transistors is - probably lots of GHz. This would be seen as a current to most scopes and applying a resistance temporarily dampens the oscillation enough for it to stop.
This would explain how it got through post-layout simulation, and first run verification tests - initial samples were just slightly different after processing. And also possibly indicate that future runs may be ok once they've got rid of the 250,000 from this batch.
