How can I use a SCXI-1100 module and 1303 terminal block to measure 0 to 1V signals without having cross-talk to other channels?

Can a 1100 module with a 1303 terminal block be used to measure a 0 to 1V signal without having cross-talk to the remaining channels?  I have been using a 1102 module up to this point but can no longer use it due to the 2Hz filter. 

I have tried all the possible combinations on the 1100 module (filters, bias & pull-up resistors, grounds, etc) that I can think of.  Is there no way to have any sort of channel to channel isolation on the 1100's?  Is there something I need to do with my VI?  Any help would be much appreciated.

Hi wpatch,

When configured correctly, you should be able to take the kind of measurement you describe without any problems. There are a number of different considerations to take when configuring your measurement, such as the signal source being used (whether it is floating or grounded and what the source impedance is) and how you have each channel wired to the SCXI-1100. Is there a specific problem you are currently encountering, and can you provide details on what kind of signal you are measuring how many channels, the scan rate, how it is connected, etc.? The best resource I can recommend is the Field Wiring and Noise Considerations for Analog Signals tutorial. You may also want to refer to the KnowledgeBase article Troubleshooting Unexpected Voltages, Floating, or Crosstalk on Analog Input Channels for further troubleshooting ideas. Hope this helps,
