NI PXI-6713I. Product Positioning and Core Features
The NI PXI-6713 is a high-performance analog output module based on the PXI bus, specifically designed for high-precision voltage/current signal generation, dynamic waveform simulation, and closed-loop control systems. Its core features include:


  • Multi-Channel High-Precision Output: 16 independent analog output channels with 16-bit resolution, supporting ±10 V voltage or 0~20 mA/4~20 mA current output to meet precision signal conditioning requirements.

  • High-Speed Update Rate: Up to 1 MS/s per channel, supporting real-time dynamic waveform generation for applications such as high-frequency response testing and motor drive control.

  • Flexible Waveform Generation: Supports DC output, arbitrary waveforms (via onboard memory buffering), and scanned waveforms (linear/logarithmic scanning) to adapt to complex signal simulation needs.

  • Synchronization and Triggering Mechanisms: Compatible with PXI trigger buses, external triggers, and hardware synchronization, enabling collaborative operation with other modules (e.g., data acquisition cards, timing modules) for multi-system synchronized control.

III. Typical Application Scenarios1. Precision Signal Source and Test Systems

  • Scenario: Testing RF modules in communication devices requires generating high-precision IQ baseband signals to drive vector signal generators.

  • Implementation: Leverage 16-bit resolution and low-noise output characteristics to generate quadrature waveforms via LabVIEW programming, synchronously output to the RF front-end through dual channels to ensure signal distortion

2. Industrial Closed-Loop Control Systems

  • Scenario: Precision platform motion control in semiconductor lithography machines requires real-time voltage signals to drive servo motors for nanometer-level positioning.

  • Implementation: Receive position feedback data in real-time via 1 MS/s high-speed update rate, compute control values, and output analog voltages through the NI PXI-6713 to drive servo amplifiers, forming a closed-loop control (response time

3. Dynamic Waveform Simulation and Emulation

  • Scenario: Simulating dynamic sensor signals (e.g., engine speed, throttle position) in automotive ECU testing.

  • Implementation: Utilize the onboard 16 kB waveform buffer to pre-store dynamic waveforms such as acceleration/deceleration curves, and replay them in real-time via hardware triggers to simulate sensor outputs under real operating conditions.

IV. Software Support and Programming InterfacesDrivers and Development Tools

  • NI-DAQmx Driver: Compatible with platforms such as LabVIEW, Python, C++, and MATLAB, providing APIs for channel configuration, waveform generation, and trigger control.

  • NI MAX: Hardware configuration tool supporting output range calibration, channel mapping setup, and real-time monitoring of output status.

  • SignalExpress: Graphical test software enabling quick generation of DC/AC waveforms without programming, ideal for prototype verification.

V. System Integration and Expansion SolutionsHardware Matching Recommendations

  • High-Precision Reference Source: Pair with the NI PXI-4130 power supply module to provide stable reference voltage for analog outputs, further enhancing output accuracy (ideal for metrology-grade testing).

  • Signal Conditioning: Use the NI SCB-68A terminal block supporting current/voltage mode conversion, filtering, and overload protection for industrial environments.

  • Multi-Module Synchronization: Collaborate with the NI PXI-6608 timing module to achieve nanosecond-level synchronization of multiple analog output cards via star trigger lines, suitable for multi-channel vibration table driving.

Performance Optimization Strategies

  • Anti-Interference Design: Use shielded cables for analog signal transmission and split ground planes (separate analog and digital grounds) to reduce EMI impact on output accuracy.

  • Real-Time Optimization: Employ DAQmx Streaming Mode with DMA direct memory access to reduce CPU load and ensure waveform stability at high update rates.
