NI PXI-4462 188261H-11L Dynamic Signal Acquisition Module

Multi-Channel Synchronous Acquisition: Supports synchronous acquisition and output of analog signals with a higher channel count, meeting the dynamic signal analysis needs of complex systems.

Upgraded Vibration & Acoustic Measurement: Compared with previous products (e.g., PXI-4461), it may optimize multi-channel collaborative performance and adapt to more sensor types (such as accelerometers, microphones, and IEPE sensors).

Real-Time Signal Processing: Equipped with a digital signal processing (DSP) chip, supporting real-time filtering, spectral analysis (FFT), windowing, and other algorithms to reduce host load.

High-Precision Synchronization: Supports clock synchronization of multiple modules, suitable for building large-scale testing systems (e.g., vehicle NVH testing, multi-point vibration monitoring networks).

Automotive NVH Testing: Synchronous acquisition and analysis of vibration and noise from multiple parts such as engines and chassis.

Industrial Equipment Health Monitoring: Multi-channel vibration spectrum analysis and fault early warning for large machinery (e.g., fans, compressors).

Acoustic Environment & Architectural Acoustics: Sound field distribution measurement and noise control in scenarios like concert halls and factory workshops.

Aerospace Structural Testing: Vibration response analysis of aircraft components and material fatigue testing.

PXI Interface: Compatible with PXI and PXI Express chassis, supporting high-speed data transmission via the PXIe bus.

Signal Interface: Connects to sensors through NI SCB-68 or SCB-44 terminal blocks, using BNC or screw terminal interfaces (supporting 8-channel input expansion).

Clock and Trigger Interface: Supports external clock input (e.g., SMA interface) and trigger signal access to achieve multi-module synchronization.

Operating Systems: Windows (7/10/11), Linux, LabVIEW Real-Time, etc.

Software Drivers: Compatible with NI-DAQmx drivers, supporting development environments such as LabVIEW, C/C++, Python, and MATLAB.

NI-DAQmx: A unified driver interface supporting multi-channel configuration and real-time data flow control.

LabVIEW: A graphical programming platform with built-in vibration analysis and acoustic measurement toolkits (such as spectral waterfall plots and octave analysis).

API Support: Provides interfaces for languages like C# and Python for easy integration into automated testing systems.

NI Sound and Vibration Measurement Suite: Includes functions such as spectral analysis, modal analysis, and order tracking, suitable for NVH testing.

NI SignalExpress: A no-code configuration tool for quickly building data acquisition and real-time display workflows.

MATLAB/Simulink: Supports data import and advanced algorithm development (such as vibration signal denoising and fault feature extraction).

Multi-Channel High-Precision Acquisition: 8-channel 24-bit ADC design, doubling the channel count compared to PXI-4461, suitable for scenarios requiring synchronous monitoring of multi-point signals (e.g., vibration acquisition from multiple parts of an engine block).

Full IEPE Integration: Each input channel supports IEPE excitation, eliminating the need for additional signal conditioning modules and simplifying the system architecture.

High-Speed Synchronization Performance: 204.8 kS/s sampling rate and low-jitter clock design ensure phase consistency of multi-channel signals and avoid testing errors.

Industrial-Grade Reliability: Wide-temperature design (for some models) and anti-interference capability, suitable for harsh laboratory and field environments (such as factory workshops and outdoor testing).
