    The channels of a multichannel PXIe-5433 are automatically synchronized when they are in the same NI-FGEN session.

    Synchronization with the NI-TClk API[30]

    NI-TClk is an API that enables system synchronization of supported PXI modules in one or more PXI chassis, which you can use with the PXIe-5433 and NI-FGEN.

    NI-TClk uses a shared Reference Clock and triggers to align the Sample Clocks of PXI modules and synchronize the distribution and reception of triggers. These signals are routed through the PXI chassis backplane without external cable connections between PXI modules in the same chassis.

    • 1 Channels support independent waveform generation.
    • 2 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.
    • 3 For example, a 5.5 Vpk-pk range equals ±2.75 V maximum offset. Offset range has a limitation of ±12 V absolute signal swing into high-impedance loads (Amplitude + |Offset| ≤ 12 V into high-impedance load or 6 V into 50 Ω load).
    • 4 Terminated with high-impedance load (load impedance set to 1 MΩ). The analog path is calibrated for amplitude, gain, and offset errors.
    • 5 Where Amplitude Range is the requested amplitude in Vpk-pk. For example, a DC signal with an amplitude range of 16 Vpk-pk and offset of 1.5 will calculate DC accuracy using the following equation: ±[(0.35% * 16 V) + (0.35% * 1.5 V) + 500 µV] = ±61.75 mV. The DC standard function always uses the 24 Vpk-pk amplitude range.
    • 6 With 50 kHz sine wave and terminated with high-impedance load.
    • 7 When the output path is disabled, the channel output is terminated to ground with a 50 Ω, 1 W resistor.
    • 8 No damage occurs if the analog output channels are shorted to ground indefinitely.
    • 9 The output terminals of multiple PXIe-5433 waveform generators can be connected together.
    • 10 Normalized to 50 kHz.
    • 11 With sine frequencies 40 MHz or higher and ambient temperatures above 45 °C, add ±0.015 dB/°C to the passband flatness specification.
    • 12 At amplitude of -1 dBFS with 0 V DC offset, measured from DC to 400 MHz, and limited to a -90 dBm spur at low amplitudes.
    • 13 Full-scale amplitude follows operation curve in Figure 11.
    • 14 At amplitude of -1 dBFS and measured from DC to the sixth harmonic.
    • 15 Noise floor is limited by the noise floor of the measurement device.
    • 16 At small amplitudes, average noise density is limited by a -154 dBm/Hz noise floor.
    • 17 With 80 MHz carrier and locked to the internal timebase with spurs removed.
    • 18 With 80 MHz carrier, integrated from 100 Hz to 100 kHz, and locked to the internal timebase.
    • 19 Used for calculating duty cycle limit: Minimum Duty Cycle = (100% * Minimum On Time) ÷ Tperiod and Maximum Duty Cycle = 100% - Minimum Duty Cycle. For more information about the relationship between minimum on/off time and duty cycle specifications, refer to
    • 20 Rise time measured from 10% to 90%.
    • 21 Rise time will vary with amplitude due to operational amplifier slew rate saturation.
    • 22 Integrated from 10 Hz to 10 MHz using a 27 MHz square wave.
    • 23 At maximum user sample rate.
    • 24 Relative to 50 kHz and at 2 Vpk-pk and maximum user sample rate.
    • 25 With the digital filter enabled and at -1 dBFS, 2 Vpk-pk, and 400 MS/s. Noise floor is limited by the noise floor of the measurement device.
    • 26 With the digital filter enabled and at -7 dBFS, 2 Vpk-pk, and 400 MS/s. Noise floor is limited by the noise floor of the measurement device.
    • 27 If locked to an external Reference Clock source, timebase accuracy is equal to the external Reference Clock accuracy.
    • 28 Where time drift starts at the latest external calibration date.
    • 29 With a 20 MHz sine wave and both channels configured with the same amplitude.
    • 30 NI-TClk synchronization support for the PXIe-5433 was first available in NI-FGEN 18.1. NI-TClk installs with NI-FGEN.
    • 31 Specifications are valid for any number of PXIe-5433 modules installed in one chassis, with each PXIe-5433 module using a single NI-FGEN session and having all analog parameters set to identical values, and Sample Clock set to 100 MS/s. For other configurations, including multi-chassis systems, contact NI Technical Support at
    • 32 Manual adjustment is the process of minimizing synchronization jitter and skew by adjusting Trigger Clock (TClk) signals using the instrument driver.
    • 33 Caused by clock and analog path delay differences.
    • 34 Synchronization jitter is the variation in module alignment across calls to NI-TClk Synchronize.
    • 35 In frequency list, arbitrary waveform, and arbitrary sequence output modes.
    • 36 Warm up begins after the chassis is powered and the PXIe-5433 is recognized by the host and configured using NI-FGEN. Self-calibration is recommended following the warm-up time.
