National Instruments introduces PXI Express Module for High-Channel-Count Dynamic Signal acquisition

摘要

National Instruments announced the NI PXIe-449x devices, the most flexible high-channel-count dynamic signal acquisition (DSA) modules Nl. The modules provide AC/DC coupling both for sensor measurements with a microphone or accelerometer and voltage measurements from a tachometer or device under test, making it possible for engineers to use a single device for all their sound and vibration acquisition needs. Michael James, VP at Blue Ridge Research and Consulting says, "We need scalable data acquisition hardware and software that yields accurate data efficiently. Leveraging LabVIEW with the Nl PXIe-449x DSA module fulfilled our needs by enabling us to customize our applications and perform real-time monitoring." The Nl PXIe-449x modules feature a choice of 8 or 16 channels with 24-bit analog-to-digital converters (ADCs) per channel and 113 dB dynamic range.
