Noise/Crosstalk

[nheft]

I am using a PCI-DIO-32HS board and an SCB-68, interconnected with a 2 meter shielded cable (SH68-68D1, p/n 183432-02) and am observing noise spikes as high as 2 volts on one signal when another signal transitions from high to low or vice versa. How is the SH69-69D1 cable wired? Is there a way to find out which signal pins are twisted against which ground pins?

Hi,

Is this a measurement on only two channels, or is this on several channels. I would try spacing the signals out, and see if you observe the same effects on a Test Panel in MAX. Let me know what happens when you try these things, and we can go from there. Have a Great Day!
