    An instrument or device that has an isolated output is a floating signal source. You must tie the ground reference of a floating signal to the AT E Series device AIGND to establish a local or onboard reference for the signal. Otherwise, the measured input signal varies as the source floats out of the common-mode input range.

    The OUT output timing parameters are referenced to the signal at the SOURCE input or to one of the internally generated clock signals on the AT E Series devices. Figure 4-37 shows the OUT signal referenced to the rising edge of a source signal. Any OUT signal state changes occur within 80 ns after the rising or falling edge of the source signal.

  • Page 102: Field Wiring Considerations

    Field Wiring Considerations Environmental noise can seriously affect the accuracy of measurements made with the AT E Series device if you do not take proper care when running signal wires between signal sources and the device. The following recommendations apply mainly to AI signal routing to the device, although they also apply to signal routing in general.

  • Page 103: Calibrating The Device

    Calibration refers to the process of minimizing measurement and output voltage errors by making small circuit adjustments. On the AT E Series devices, these adjustments take the form of writing values to onboard calibration DACs (CalDACs).

  • Page 104: Self-Calibration

    Self-Calibration The AT E Series device can measure and correct for almost all of its calibration-related errors without any external signal connections. The NI software provides a self-calibration method you can use. This self-calibration process, which generally takes less than a minute, is the preferred method of assuring accuracy in your application.

  • Page 105: Other Considerations

    16-bit device, the external reference should be at least ±0.001% (±10 ppm) accurate. For a detailed calibration procedure for the AT E Series device, refer to the E Series Calibration Procedure by clicking Manual Calibration Procedures at Other Considerations The CalDACs adjust the gain error of each AO channel by adjusting the value of the reference voltage supplied to that channel.
