CompactWCA

User-friendly GUI with greater ease of operation
A workflow-orientated menu will help the operator reduce system setup time and boost testing productivity.

Complete compatibility with the WCAonPC / AD-3600 series
A compatible user interface eliminates the need for additional training of WCAonPC / AD-3600 users. In additon, 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).
