National Instruments PXIe-4481 PXI Analog Input Module

The 24-Bit, 6-Channel, 1.25 MS/s/ch, PXIe‑4481 (Part Number: 784278-01) is an Analog Input Module for higher data transmission voltage estimations. The module offers analog and digital filtering for precise frequency area estimations. The user can choose from four gain settings to arrange the input range. For estimating sudden changes, such as rapid blast and pressure events, the NI PXIe 4481 can test up to 20 MS/s per channel in time area mode. The included NI-DAQmx driver simplifies hardware configuration and estimation. This model also gives dynamic signal generation and acquisition in sound and vibration applications for PXI frameworks.

PXI Sound and Vibration Modules are composed particularly for applications like sound test and estimation, noise and vibration diagnostics, machine condition monitoring, automotive test, noise, vibration, and harshness (NVH) examination, and laboratory research. They give programming configurable AC/DC coupling, antialiasing channels, and IEPE conditioning to guarantee accuracy estimations with microphones, accelerometers, and different transducers with extensive powerful ranges. The user can arrange the NI PXIe-4481 module for either AC or DC coupling. If the user selects DC coupling, any DC offset present in the source signal is passed to the ADC. The DC-coupled setup is typically best if the signal source has only little measures of counterbalance voltage or if the DC content of the acquired signal is important. If the source has a lot of unwanted offset, the user can select AC coupling to take full advantage of the input dynamic range.
