Something weird is happening with the hrtim master period
...
This new value gives much cleaner curves. I suspect that either we have
some issue with ADC sampling not being precise due to clock domain
crossings, or this is just interference and the new period hits a sweet
spot that is coherent with this interference.

Move stimulus instead of sampling pulse, eliminates ADC alignment issue
...
The ADC can only trigger on whole clock pulses, so when we move the
sampling pulse in fractional increments, the relative alignment of the
ADC's sampling phase w.r.t. sampling pulse moves around +/-0.5 clock
periods. Since our opamps ring a bit, that leads to an artifact in the
measurements with a period of 32 samples (one whole clock pulse). Moving
the stimulus pulse instead fixes this issue, as now the alignment
between the sampling pulse and the ADC's sampling is constant.
