    Calibration

    External Calibration

    The external calibration calibrates the ADC voltage reference and passband flatness. Appropriate constants are stored in nonvolatile memory.

    Self-Calibration

    An onboard, 24-bit ADC and precision voltage reference are used to calibrate the DC gain and offset. Onboard channel alignment circuitry is used to calibrate the skew between channels. The self-calibration is initiated by the user through the software and takes approximately 60 seconds to complete. Appropriate constants are stored in nonvolatile memory.

    • 1 Single-ended output available on main path only.
    • 2 Applies to differential, common-mode, and single-ended offsets.
    • 3 For all configurations, both CH± terminals are terminated to ground through loads of the same value.

      The voltage output levels are set in the software and are based on a 50 Ω per line load termination to ground (the default) or based on the user-specified load resistance. Common-mode offset assumes output terminals are terminated into equal loads to ground. Gain values in NI-FGEN correspond to Vpk, which is half the amplitude in Vpk-pk.

      Combinations of waveform data, offset, and gain that exceed a single-ended output of 3.2 Vpk may result in waveform clipping.

    • 4 Amplitude values assume the full scale of the DAC is used. If an amplitude smaller than the minimum value is desired, you can use waveforms less than the full scale of the DAC, or you can use digital gain. Additional offset can be added using waveform data.
    • 5 Measured on CH+. Vpk on each terminal is equal to Analog Offset + Waveform Data * Gain.
    • 6 Measured as differential peak-to-peak signal amplitude (Vpk-pk). Each terminal Vpk-pk is half of the differential Vpk-pk. Vpk on each terminal is equal to Differential Offset * 0.5 + Common-Mode Offset + Waveform Data × Gain/2.
    • 7 Both CH 0+/- or CH 1+/- terminals are terminated to ground through loads of the same value. Single-ended values are half of differential values.
    • 8 For the Main path, VCM +VDIFF/2 and VCM – VDIFF/2 is between ±2 V, into an open load.

      For all configurations, both CH± terminals are terminated to ground through loads of the same value.

      The voltage output levels are set in the software and are based on a 50 Ω per line load termination to ground (the default) or based on the user-specified load resistance. Common-mode offset assumes output terminals are terminated into equal loads to ground.

    • 9 Both CH 0+/– or CH 1+/– terminals are terminated to ground through loads of the same value. Offset is any combination of common-mode offset voltage and differential offset voltage.
    • 10 Additional offset can be added using waveform data.
    • 11 Combinations of waveform data, offset, and gain that exceed a single-ended peak output voltage of 3.2 V may result in waveform clipping.
    • 12 ±5 °C of self-calibration temperature. Alignment can be improved with manual adjustment by using Sample Clock Delay.
    • 13 Measured with a DMM. Measured with both output terminals terminated to ground through a high impedance. For the differential direct path, differential offset is not adjusted during self-calibration.
    • 14 For DC accuracy, single-ended output range is defined as 2x the gain setting into high impedance. For example, the accuracy of a DC signal with a gain of 2.5, a load impedance of 1 GΩ, and a single-ended output range of 5 V is calculated using the following equations:

      Gain error within ±5 °C of self-cal temperature: ±(0.4% * 5 V + 0.5 mV) = ±20.5 mV

      Gain error at +10 °C of self-cal temperature: ±20.5 mV - 0.05% * 5 °C * (5 V) = +8 mV/-33 mV

      Offset error: [2 V Offset at Gain = 2.5 ] ±(0.15% * (2 V) + 0.04% * (5 V) + 1.25 mV) = ±6 .25 mV

    • 15 For DC accuracy, differential output range is defined as 2x the gain setting into high impedance. For example, the accuracy of a DC signal with a gain of 5, a load impedance of 1 GΩ, and a differential output range of 10 V is calculated using the following equations:

      Gain error within ±5 °C of self-cal temperature: ±(0.6% * 10 V + 1 mV) = ±61 mV

      Gain error at +10 °C of self-cal temperature: ±61 mV - 0.05% * 5 °C * (10 V) = +36 mV/-86 mV

      Differential offset error: [Requested Differential Offset = 1 V at Gain = 5] ±(0.3% * (1 V) + 0.01% * (10 V) + 2 mV) = ±6 mV

    • 16 Direct path common-mode offset is minimized through active circuitry. Applying an external nonzero common-mode offset to the output terminal is not recommended; however, the common-mode circuitry can sink or source up to 5 mA of common-mode bias current. Terminate both output terminals to ground through the same impedance. If the output terminals are not terminated to ground, the maximum termination voltage is 250 mV through 50 Ω.
    • 17 Within ±5 °C of self-calibration temperature. Measured using a DMM, with full-scale data into high impedance, 50 kHz sine wave, 400 MS/s. The output range defined in DC Accuracy must be converted to VRMS by dividing by (2√2).
    • 18 Both output terminals must be terminated with the same impedance to ground.
    • 19 The voltage output levels are set in the software and are based on a 50 Ω per line load termination to ground (the default) or based on the user-specified load resistance. Common-mode offset assumes output terminals are terminated into equal loads to ground.
    • 20 Both CH 0+/– or CH 1+/– terminals are terminated to ground through loads of the same value.
    • 21 Clipping may occur if the summed voltage is outside the maximum voltage range.

For channel-to-channel passband flatness matching enabled: With respect to 50 kHz on each channel, 400 MS/s. Load variations may degrade performance. Refer to the AC Amplitude Accuracy Main Path specification for the correct terminal configuration for the 50 kHz reference accuracy.
    • 25 For channel-to-channel passband flatness matching disabled: With respect to 50 kHz into 100 Ω differential load, 400 MS/s. Flatness correction corrects for analog frequency response and DAC sinc response up to 0.3 × sample rate. Receiver return loss may degrade flatness. For channel-to-channel passband flatness matching enabled: With respect to 50 kHz on each channel, 400 MS/s. Load variations may degrade performance. Refer to the AC Amplitude Accuracy Direct Path specification for the correct terminal configuration for the 50 kHz reference accuracy.

      For cells with two values, the first specification listed is for a 10.0 MHz sinusoid at a 400 MS/s sample rate (waveform contains 40 unique samples), and the specification in parentheses is for a 10.0 MHz sinusoid at a 399.9 MS/s sample rate (waveform contains over 3,000 unique samples with unique DAC codes). Long, non-repetitive waveforms like modulated signals offer better spurious performance. For periodic waveforms represented by a small number of unique samples, DAC nonlinearities limit dynamic specifications.

    • 70 For example, for a Sample clock rate of 400 MS/s, I/Q rate range = 12.2 kS/s to 200 MS/s.
    • 71 Data Processing Mode describes the OSP engine data source. The data can be a single stream of real data (Real), or separate streams of real and imaginary data (Complex).
    • 72 OSP Mode describes the signal processing function performed on the data after interpolation. In IF Mode, I and Q data streams are quadrature upconverted to an intermediate frequency in a single output stream (to DAC 0/I). In Baseband Mode, frequency shifting can be applied to the I and Q data streams before they go into separate output streams (DAC 0/I and DAC 1/Q).
