Data acquisition with Soundbook and AMADEUS:
modular, scaleable up to 40 synchronized channels
The new Soundbook_Expander offers 8 fast 24-bit measurement channels as a USB device. Simply plug-in the Expander and start the measurement!
The Soundbook_Expander extends the Soundbook™ measuring system with 8 additional measurement channels and many additional service channels. In addition to its application as a channel extension for Soundbook, the Expander can also be used as a free-standing data acquisition device with a Windows PC. Up to 4 Expanders (and additionally a Soundbook) can be used together sample-synchronously with the aid of the Sync_Hub. In this way it is possible to configure measurement systems with 8 ... 40 measurement channels for an extremely wide range of applications. This flexible, portable measurement system is, due to its high signal bandwidth, its wide dynamic range and its integrated sensor power supplies, suitable for all professional applications in acoustics and vibration measurement. The Expander hardware is fully compatible with Soundbook_MK2 and is based upon the innovative Apollo™ platform. According to your requirements you may choose from variants having 8x LEMO7 or 8x BNC input connectors. The additional 8 slow channels, 2 Tacho & Trigger channels, Synchronization port and AUX port allow for universal application of the device.
The connection between Soundbook_MK2 and the Expander is via a special USB cable for the data together with a separate synchronization cable. These cables are included in the scope of delivery with a length of 10 cm for direct device mounting and 5 m for separated use. When a Sync-Hub is used, the system is provided with power via the mains adapter supplied.
Our universal AMADEUS software offers all functions necessary for measurement and analysis of sound and vibration according to standards, both in real-time and as post-processing. The intuitive user interface, high flexibility and many options of SAMURAI 2.2 make Soundbook, the Soundbook_Expander and the Apollo_Box into extremely robust and popular tools for:
  • Engineering services
  • Quality assurance
  • Research and development.
In particular for raw signal acquisition in many-channel applications, all devices based upon the new Apollo™ platform with SAMURAI 2.2 provide the advantage of a drastic reduction of the data volume via:
  • channel-specific sample rates and
  • the possibility of low-loss compression (OggVorbis).
For applications in machine diagnosis and for custom programming of the devices on the basis of our unified Windows device driver we also offer the following alternative software solutions:
  • µREMUS for mechanical investigations
  • SMT (SINUS Matlab Toolbox) for custom programming
In combination with the modular software packages offered, the Expander can be employed for the following applications (and more):
  • Sound level measurement
  • Frequency analysis
  • Signal recording
  • Human vibration measurement
  • Building vibration measurement
  • Building and room acoustics
  • Machine vibration measurement
  • Modal analysis
  • Order tracking analysis
  • Operational vibration analysis
