ORCHESTRA

The Ultimate Compact Real-time Data Acquisition Front End
and Frequency Analyser

Orchestra is made up of one or several modular multichannel hardware units and of the 01dB-METRAVIB software suite dedicated to real-time data recording and frequency analysis. Orchestra is a configurable and modular system containing separate and independent hardware modules. No main frame is needed and all modules can be mounted very easily.

 

Three kinds of modules can be mounted together:

  • Interface module allowing connection to PC through Firewire interface (IEEE 1394)
  • Input module for 4 transducers with conditioning and 16/24 bits A/D conversion
  • Function module adding features like generator

One interface unit can manage up to 24 channels (6 input modules). Independent frequency sampling can be used on each input module. Several different input modules are available for Direct voltage/IEPE* transducers, Microphones, Charge accelerometers, Strain gage sensors,...

Key Features
