I am using the LSM6DSL for a high frequency vibration measurement involving the accelerometer sensor only (gyroscope is turned off). Output data rates are variable between 400-3.3kHz. A recent frequency sweep experiment (0-6kHz applied on external sp...

Hello Eleon,Do you have any updates for this? We have since tried simultaneously sampling two LSM6DSL accelerometers at 6.6kHz and inputting a 10-15kHz sweep. As far as the documentation shows, the highest analog anti-aliasing filter possible should ...

3 - data_1-001.csv corresponds to a data set taken on a pediatric subject. You can see in the attached spectrogram that the harmonics of the voice are reflecting off of the nyquist frequency and aliasing down to interfere with the fundamental frequen...

2 - data_constant_sweeps.csv corresponds to a different device and firmware which uses the LSM6DSL, sampling at 1.6kHz. The device was placed on a speaker and 4 linear frequency sweeps were performed. First a sine wave 0-1.5kHz. Then a triangle wave...

Hello Eleon,Thanks for looking into this. The short answer is yes, we've noticed this across different devices as well as using firmware/drivers developed separately. I have attached three data sets (not letting me upload all at once so will try sepa...
