pcb333b50 accelerometer with NI 9232 Screw Terminal Connector

[RezaJohn]

Hello,

I have been trying to acquire data from my accelerometers with NI 9232. I have a periodic noise in my signals. For connection, I cut the usual wire to connect the accelerometer to the screw terminal connector. I am still not sure if this is the problem or not? I have attached one of these signals with its double integration from it.

Thanks

The periodic noise shown in 1.jpg only occurs after the impulse(trigger). I am not sure it is noise/pickup. If it was it would be evident for all times.
