204.8 kS/s, 4-Input PXI Sound and Vibration Module

Overview

The PXI-4462 is designed for sound and vibration applications. It provides four-channel dynamic signal acquisition for making high-accuracy frequency-domain measurements, and you can use one of six gain settings to configure your input range. The PXI-4462 also includes software-configurable AC/DC coupling and IEPE conditioning. The PXI-4462 includes the hardware and software needed to make precision measurements with microphones, accelerometers, and other transducers that have very large dynamic ranges. Common applications include audio test; automotive noise, vibration, and harshness (NVH); and machine condition monitoring.

Product (Part Number) Description	Recommended use cases
FlexLogger Professional (785748-3501) FlexLogger Professional, Subscription License, Download	Recommended for automated, extensible data logging with NI data acquisition (DAQ) hardware. Automate tests using alarms, triggers, and events, and expand capabilities with plug-ins. Key Features Multichassis synchronization—Synchronize multiple NI chassis for accurate, time-aligned measurements across high channel counts. Logging triggers—Start, stop, or segment data recording automatically based on sensor thresholds or other conditions to capture only what matters. Events—Respond to specific occurrences during a test, such as activating equipment when a condition is met (for example, start cooling fans when temperature exceeds a limit). Automation APIs—Control and monitor FlexLogger from external applications (Python, NI LabVIEW, or NI TestStand), enabling integration into larger automated test systems. Calculation channels—Perform real-time math on acquired data (averages, RMS, custom formulas) to track derived measurements as the test runs. Plug-ins—Extend FlexLogger with custom LabVIEW or Python plug-ins to integrate third-party hardware, perform custom analysis, or connect to lab systems. CAN/LIN logging—Acquire and log automotive network data alongside sensor measurements for complete vehicle or subsystem testing.	View Product Details
