PCIe-6321 analog input noise problem

[EOD_Mühendislik]

Hello Everyone. 

I hope, you are all well. 

I have an interesting noise problem in my NI PCIe-6321-----SCB-68A----SHC68-68-EPM daq system. 

Explanation: I am using siemens driver and 4 vacuum sensors in my system. And this noise only happening when the motor is drive on. 

Please look at the picture or video to understand what kind noise the system is taking. Every graph is belong to one vacuum sensor. 

I took this grahp under these condition:

Motor is drive on

Motor is not moving.

All cable is shielded and ground well. 

Thanks

Ozan.
