Tool/software:
Hi everyone,
I’m currently using the ADS1298ECGFE-PDK to acquire EEG/EMG signals from throat muscles, but I’m facing difficulties in getting usable data and would appreciate any suggestions.
I’m not sure whether the issue lies with my setup or if the board itself might be damaged, so I’m sharing the details below in the hope of getting some guidance.
I’m using only 4 electrodes on the following pins below, but I’m experiencing a lot of noise — especially when using a 6V power adapter. After raising the issue with the TI team and following the guidebook instructions,
I tested the kit using a battery pack supply but I’m still facing the same issue. It seems the problem isn’t just noise — my concern is even if this kit is functioning correctly or damaged? As the signals appear very random.
I’ve tried both medical-grade (reusable AU/ AG plated electrodes) and disposable electrodes, but the results remain the same. While I understand some level of noise is expected, I would still expect some usable EMG/EEG signals during muscle movements. However, the data quality seems unusable.
I’m attaching a screenshot of one of the signals for reference. Currently, I’m using only 4 electrodes with the following pin configuration:
-
Pin 9 – RA
-
Pin 10 – LA
-
Pin 11 – LL
-
Pin 14 – RL
Could you please review this and let me know if my setup might be incorrect or if there’s something else, I should try? Appreciate Feedback and suggestion 
Thanks
Mani
