Hello Virginie,

We have not started use of our MaxShield system, because of those additional jumps we too saw in our data. We heard we will be getting a firmware fix for Maxshield soon.

The data are displayed with SSP off, 32 bit mode, no Maxshield, 1000 s/sec, 0.1 Hz to 330 Hz standard acquisition filtering.

Hello all,

Are these recordings obtained with MaxShield on?

We had similar issues except they required a resetting due to a very slow drift (10 min) of the feedback sensors used in Maxshield.With maxshield off, no such problems are observed. Those sensors will be re-tuned next week.
