[time-nuts] Tbolt failure modes

[J. L. Trantham]

Today I 'failed' the -12 V supply again and got screen captures of the
TBoltMon GUI with the TBolt operating normally, -12V failed short and -12V
failed open.

I used a 5372A referenced to a Z3816A to measure the 10 MHz output frequency
of the TBolt for normal operation followed by -12V failed short then -12V
failed open.

It would appear that the DAC voltage displayed is unreliable/inaccurate when
-12V fails.

I would be happy to send them to anyone who wants them.
