Spikes in dZ/dt

[AMSuser Profile]

Hi again

We discovered some sort of spikes in the dZ/dt channel:

We also noticed a sort of wishbone like periodic repetitive signal in the raw motility channels:

Do you have any idea what could be the problem?

Hi again AMS user,

This is clearly a hardware problem! Please contact us via vu-ams@psy.vu.nl so we can arrange the necessary hardware repair.

Best,

Please see the temporary solution below:

The hardware problem is a connector inside the device is not gold plated and has to be replaced. If you can’t miss the device you can postpone our repair by dropping the VU-AMS device from about 20cm on a hard surface like a desk without any connectors attached (I’m not joking). This will make the connector move a little and clean the contact (for a while). This also explains why the problem might seem to disappear sometimes if you would be looking at previously recorded data.

Best,
Jarik
