  • Complete compatibility with the WCA on PC / AD-3600 series
    A compatible user interface eliminates the need for additional training of WCA on PC / AD-3600 users. In addition, all prior analysis data remains upward compatible with Compact WCA.
  • Compact-True ISO A4 Size (210 x 297mm)
    You can use the CWCA anywhere; on-board a vehicle, in the field or in the lab, using DC or AC power both available with optional battery backup to protect data loss during power interruptions.
  • The Compact WCA system from 4, 8 to 16 channels with single front-end hardware.
    Expansion to a 32-ch, 48-ch or 64-ch configuration is possible with a synchronized connection of several 16-channel front-ends. Flexibility is provided to allow two separate mainframes with 4, 8, or 16 channels to be operated as a single 8, 16, or 32 channel system, and vice versa, by synchronizing the dual mainframes.
  • Flexible Menu Customization / Routine Automation
    COM support capability enables complete control of the Compact WCA system with external application software such as Microsoft Excel. Customized menu design and automated routine processing are possible.

  • Powerful Analysis Software
    Multi-Analysis Software WCA PRO
    WCA Pro, the base software for Compact WCA, can be used with Windows user interface. WCA Pro provides real-time FFT analysis for noise & vibration testing.

    Optional licenses for integrating real-time octave analysis and tracking analysis are available. The system comes standard with throughput acquisition, allowing continuous copying of time history data to disk and repeated playback analyses. Off-line playback analysis with a standalone PC is also possible (option).
