crosstalk in DAQ

[labmaster]

I have used the USB-6229, BNC type in the differential mode of DAQ.

Channel 0 : pressure gauge

Channel 1 : microphone

Two signals are independent and don't share the ground.

I set the FS in USB-6229. 

When I open the channel0 (by pulling the BNC), I found the singla of channel1(crosstalk).

I am very wondering if the crosstalk exists in normal measurement of channel0.

Would you please guide me how to shoot this trouble?

I got to know my question was boring to you.

I found the solution. thanks to NI forum.
