Awg issue
We are having troubles with the drive generated by awg. For some period of times it goes "weird". It can trip the watchdogs as illustrated on the attached document. 

On this example:
- the drive is good at the beginning
- then it starts doing unwanted high frequency stuff
- then it does other unwanted "oscillations" at frequencies coinciding sufficiently with the HAM-ISI resonance to trip the watch dogs. This is preventing us from completing our measurements.
