    Last Modified: May 4, 2017

    Definitions

    Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

    Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

    • Typical specifications describe the expected performance met by a majority of the models.
    • Nominal specifications describe parameters and attributes that may be useful in operation.

    Specifications are Nominal unless otherwise noted.

    Maximum output overload

    The CH 0 output can be connected to a 50 Ω, ±12 V (±8 V for the direct path) source without sustaining any damage. No damage occurs if the CH 0 output is shorted to ground indefinitely.

    Waveform summing

    • 1 Depending on the value of the Gain property or NIFGEN_ATTR_GAIN attribute, either the low-gain amplifier or the high-gain amplifier is used when the main output path is selected.
    • 2 The direct path is optimized for intermediate frequency (IF) applications.
    • 3 The maximum output voltage of the PXI-5421 is determined by the amplitude range and the offset range.
    • 4 Amplitude values assume the full scale of the DAC is utilized. NI-FGEN uses waveforms less than the full scale of the DAC to create amplitudes smaller than the minimum value. NI-FGEN compensates for user-specified resistive loads.
    • 5 Offset range is not available on the direct path.
    • 6 For DC accuracy, amplitude range is defined as two times the gain setting. For example, a DC signal with a gain of eight has an amplitude range of 16 V. If this signal has an offset of 1.5, DC accuracy is calculated by the following equation: ±0.2% * (16 V) ± 0.05% * (1.5 V) ± 500µV = ±33.25 mV
    • 7 50 kHz sine wave.
    • 8 Measured at -3 dB.

    • 15 Amplitude -1 decibel full scale (dBFS). Measured from DC to 50 MHz. SINAD at low amplitudes is limited by a -148 dBm/Hz noise floor.
    • 16 Amplitude -1 dBFS. Measured from DC to 50 MHz. Also called harmonic distortion. SFDR with harmonics at low amplitudes is limited by a -148 dBm/Hz noise floor.
    • 17 Amplitude -1 dBFS. Measured from DC to 50 MHz. SFDR without harmonics at low amplitudes is limited by a -148 dBm/Hz noise floor.

    • 33 Tested with 100 Ω differential load, measured at the device front panel, load capacitance <10 pF, driver and receiver comply with ANSI/TIA/EIA-644.
    • 34 Skew between any two output terminals on the DIGITAL DATA & CONTROL (DDC) front panel connector.
    • 35 In arbitrary waveform mode, a single waveform is selected from the set of waveforms stored in onboard memory and generated.
    • 36 In arbitrary sequence mode, a sequence directs the PXI-5421 to generate a set of waveforms in a specific order. Elements of the sequence are referred to as segments. Each segment is associated with a set of instructions. The instructions identify which waveform is selected from the set of waveforms in memory, how many loops (iterations) of the waveform are generated, and at which sample in the waveform a marker output signal is sent.
