  • 1 Noise is specified as two-sigma (at three-sigma confidence) after zero operation when measured with 10.2 seconds of measurement time (measurement time = Aperture Time * Number of Averages). Effect of noise can be reduced by increasing the number of averages and/or increasing the aperture time. Noise decreases at a rate equal to the square root of the number of averages and aperture time.

    2 Zero set is specified as the mean (at three-sigma confidence) after zero operation when measured with 256 averages and 40 ms aperture time for 1 hour, and when keeping the temperature within ±1 ºC.

    3 Zero drift is specified as two-sigma (at three-sigma confidence) after zero operation when measured with 256 averages and 40 ms aperture time for 1 hour, and when keeping the temperature within ±1 ºC.

    4 Measurement error with reference to a CW signal of equal power and frequency at 20 ºC to 30 ºC.

    5 Maximum number of averages allowed in Continuous mode and Time Slot mode is 65,536. In Scope mode, the maximum number of averages is equal to 16,777,216 divided by the number of data points.

    6 Averaging resolution of 0.001 dB is not available with the NI-568x SFP. This feature is only available when using the NI-568x instrument driver. Averaging resolution is defined as the place after the decimal to which the reading becomes stable.

    7 Times are typical based on benchmark results taken using an NI PXIe-8135 controller and an USB-5683. Performance may vary based on system configuration. Trigger source set to Immediate. Number of Averages = 1 for repeat average mode.

    8 Times are typical based on benchmark results taken using an NI PXIe-8135 controller and an USB-5683. Performance may vary based on system configuration. Trigger source set to Immediate. Number of Averages = 1 for repeat average mode.

    9 The start exclusion time plus the end exclusion time must be less than the slot width.

    10 Software trigger not available in the NI-568x SFP. This feature is only available when using the NI-568x instrument driver. Internal and external triggers are not available when using Continuous acquisition mode.

    11 Latency is defined as the time delay between the sensor receiving the trigger and the measurement initiation.
