Compatible with the NI Sound and Vibration Measurement Suite, a collection of analysis and signal processing tools, a wireless data acquisition module and two PXI Express modules from National Instruments offer improved performance over previous devices of this type. The WLS-9234 wireless dynamic signal acquisition (DSA) module can stream vibration data wirelessly via IEEE 802.11g (Wi-Fi) to distributed monitoring systems. The PXIe-4496 and PXIe-4498 PXI Express DSA modules can acquire data from 272 channels at full rate in a single PXI Express chassis. The WLS-9234 has four 24-bit resolution simultaneously-acquired input channels with a 51.2 kS/s max sampling rate with 102 dB of dynamic range. The PXIe-4496 and PXIe-4498 offer 16 24-bit resolution simultaneously-acquired channels with 204.8 kS/s max sampling rates with a 113-dB dynamic range. From $1,999.
