NOISE - ADXL1005 eval board, Teensy 4.0, ADS1256

Category: Hardware
Product Number: EVAL-ADXL1005Z

Hello,

I have vibration analyzer made from Teensy 4.0, ADS1256 eval board and ADXL1005 eval board.
I have app in Python to read data from Teensy. I have sample rate 30k. Sending to Windows via USB (and powered from USB). But I have lot of noise.

Maybe you can show me the way how lower the noise. If I use USB isolator ADUM4160/ADUM3160, it is better. But is any way how to do it without USB isolator?
Thanks

Michal
