Noisy Analogue Signals From SCB-68

Hi,

 

I have a set up as shown below. 

 

Futek Load Cells >> SCC-SG04>> SC-2345 >>SH68-68EP Cable >> SCB-68 >> Analogue input of PCI 7350 8 axis motion controller.

 

This set up has resulted in a noisy analogue signal from 7350 with high amplitude spike. 

 

 

I had tried to check the signal from load cell by connecting load cells >> SCC-SG04 >> SC-2345 >> M-Series DAQ card, the reading was fairly smooth with no spikes. Therefore, i suspect the noise was picked up in the connections for SCB-68.

 

Is this set-up correct to connect the load cell signals to PCI-7350? If so, how can I reduce the noise picked up from the connections?

 

Thanks for helping.
