Summary Of Testing
These are the results of the tests that have been conducted in the FEE alcove to determine if the XPM glitch can be reproduced.
Every test is run from a starting behavior where the DAQ can allocate, configure, run, and disable.
Whenever the DAQ does not follow the starting behavior remedies are applied to recover it.
