    Why am I seeing crosstalk when sampling multiple NI I/O Systems channels?
    • J

      Crosstalk or ghost voltages when sampling multiple channels on NI I/O Systems 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. Alternatively, 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.

    What to do if NI I/O Systems readings are random in differential analog input ground-reference mode?

      Jaime LarsenAug 20, 2025
      If you observe random readings with rapid drift in differential analog input ground-reference mode on your NI I/O Systems device, check the ground-reference connections. Also, ensure that the signal is referenced to the same ground level as the device reference.

    How to fix glitches on the output signal of NI PCIe-6374?

      Luke SpencerAug 29, 2025
      Glitches on the output signal of NI I/O Systems can occur when a DAC switches from one voltage to another. To mitigate this, build a lowpass deglitching filter to remove some of these glitches.
