PXI-4496

Part number(s):

779748-01

204.8 kS/s, 114 dB, 2 Gains, 0.5 Hz AC-Coupled, 16-Input PXI Sound and Vibration Module

Overview

The PXI-4496 is designed for high-channel-count sound and vibration applications. With 24-bit analog inputs and IEPE constant current signal conditioning, the PXI-4496 is ideal for making precision measurements with microphones, accelerometers, and other transducers that have very large dynamic ranges. The PXI-4496 delivers simultaneous sampling on all channels. In addition, the PXI-4496 includes built-in antialiasing filters that automatically adjust to your sampling rate and software-selectable input gains up to 20 dB, and TEDS smart sensor support for error-free setup. Common applications include noise, vibration, and harshness (NVH) analysis, large microphone arrays, and dynamic structural test.

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
