Hi, I'm using Cypress 68013 to transfer the data from Medical Device EEG amplifier to computer with high-speed USB.

When transferring, there is a high frequency knife working around the EEG device. The high-frequency electromagnet wave will interrupt the USB transfer.  

Would you please help to give some possible solutions to solve the USB working with the high frequency knife?

Thanks,

Allen

Hi, Varun Narolkar

Very Glad to hear your rapid reply.

Here is my schematic.

I'm using the MCU STM32F407 to transfer the signals from AD to Cypress 68013.

Thanks,

Allen
