Why am I seeing crosstalk when sampling multiple channels with National Instruments Data Loggers?

Crosstalk or ghost voltages during multi-channel sampling can occur due to charge injection. To resolve this, use a voltage follower with operational amplifiers (op-amps) with unity gain for each high-impedance source before connecting to an X Series device. Also, decrease the sample rate for each channel. If you are sampling among multiple channels at various gains, refer to the Multichannel Scanning Considerations section of Chapter 4, Analog Input.
