Part Number: ADS1292R Tool/software: Hello, TI engineers! I only used one ADS1292R to test one channel of ECG and one channel of respiration. I have a question about the sampling rate of ADS1292R. When I set the sample rate to 500Hz, the actual sampled and recorded data is not that much, and the fluctuation is large. What is the reason for this situation? Some of my output logs are as follows: ECG sample rate: 206.0 Hz ECG sample rate: 160.199 Hz ECG sample rate: 247.75224 Hz ECG sample rate: 139.58125 Hz ECG sample rate: 130.86913 Hz ECG sample rate: 108.0 Hz ECG sample rate: 330.7241 Hz ECG sample rate: 437.68692 Hz ECG sample rate: 407.59238 Hz ECG sample rate: 439.0 Hz ECG sample rate: 448.0 Hz ECG sample rate: 436.255 Hz ECG sample rate: 393.76218 Hz ECG sample rate: 451.0 Hz ECG sample rate: 382.0 Hz ECG sample rate: 466.53345 Hz ECG sample rate: 429.5704 Hz ECG sample rate: 417.0 Hz ECG sample rate: 462.53745 Hz
