Hi.
I use ads1294 and program it's register for internally short circuit with G = 12 , Fs=2000 SPS , Vref = 4v,
after capture data , I plot PSD of 4 channels and I see an signal in about 800 Hz only in channel 3 ?
(when I use external signa fed to ADS1294, this noise is on.)why Channel 3 on ADS1294 has an unwanted signal in about 800 Hz ?why this happened and how I can eliminate it ?
Thank you.
