Hi Ntumsl,

Thank you for your inquiry and allow me to introduce myself as the Support Manager here at Delsys.

The Trigno IM sensors when streamed via the SDK sample at a fixed 2000 Hz (ensures synchronization and prevents under-sampling). For your external analog devices, I believe Nexus may have some control over the sampling rate if you do not need this to be set as high at 6000 Hz, thus helping to shrink some of those data files.

If anything remains unclear, please feel free to reach out to our team of engineers at support@delsys.com or give us a call at (508) 545-8200.

Best regards,
Brian
