AFE4960EVM: Support Request: Adjusting Data Rate for 5-Lead ECG Acquisition Using AFE4960 EVM

Part Number: AFE4960EVM
Other Parts Discussed in Thread: AFE4960

Tool/software:

Hi Team,

We are currently using the AFE4960 EVM to collect 5-lead ECG data through the Bio Sensing and AFE4960 GUI applications. Our configuration is based on the DUAL_AFE_3ECG_1RESP.py script provided in the Bio Sensing application to support a 5-lead ECG setup.

We would like to collect ECG data at 1000 samples per second (SPS) and 256 SPS, depending on the use case.

Questions:

  1. How can we change the data sampling rate to 1000 SPS and 256 SPS within the current setup?

  2. Are there specific parameters in the DUAL_AFE_3ECG_1RESP.py script or in the GUI that need to be modified to support these data rates?

  3. Are there any additional configuration steps we should follow to ensure proper data acquisition at these rates?

Your guidance on configuring the EVM and software tools for the desired sampling rates would be greatly appreciated.

Best regards,
Vedashree
