J. Kissel,
 
While tuning the drive amplitudes on some explorative transfer functions regarding the UIM actuation discrepancy, I aborted a measurement which resulted in a huge spike from my excitation channels (much higher than my requested excitation) and broke the lock.

This remains an open CDS Bug, open since this past July (see Bug 897); hopefully now that the run is over, we can install some updates to software such that this finally gets fixed.
