High-Speed Multi-Channel Data Acquisition

Recently, we supplied a high-speed multi-channel data acquisition system to an aerospace company. The system comprises several sub-systems each housed in a separate steel box made by Zarges. These anti-vibration, vapour-proof boxes guarantee optimal protection of the valuable electronics. Each box includes an industrial PC and a UPS. The hardware consists of Spectrum PCI Express cards and portable m+p VibMobile front-ends and is configured as follows:

  • six 16-channel systems up to 1.33 MHz (Spectrum M2i-4741-exp)
  • two 32-channel systems up to 1.33 MHz (Spectrum M2i-4741-exp)
  • two 16-channel systems up to 125 MHz (Spectrum m2p.5962-x4)
  • two 16/24-channel systems up to 102.4 kHz (m+p VibMobile BR810 bridge modules with thermocouple amplifier)

The hardware is fully integrated into our m+p Analyzer to allow user-friendly setup and dynamic signal acquisition. Depending on the selected sample rate and number of used channels, the Spectrum based system can acquire some seconds of data in its internal memory. After completion of the test, this data is written to a SOT file on the PC's hard disk for further processing and comprehensive report generation using m+p Analyzer.
