How do I eliminate cross talk from scxi 1102c?

[banj]

I'm attempting to aquire data from 3 accelerometers that give me a reading between -10 and 10 volts. I'm reading at 6000scans/sec. If I read them all by themselves I can capture there individual signals but when I try to read them at the same time I only get one signal. I've tried shorting out all of my unused channels and setting me interchannel delay to the maximum but nothing changes. What can I do to eliminate the cross talk.

thanks in advance for any help,

Cross-talk can be caused by inputs with a high source impedance. If your inputs have a source impedance over 1 Kohm, then that might be causing the cross-talk. There are documents on our website that discuss ways to decrease the source impedance to eliminate cross-talk. I've included links below to these documents. I hope this helps.
