 CompactWCA

友好的图形界面,极易操作
以工作流程为导向的菜单可以帮助操作员减少系统设置时间,提高测试工作效率。

与WCAonPC/AD-3600完美兼容
一个兼容的用户界面,现有的WCAonPC/AD-3600用户无需额外培训。此外,所有过去的数据仍然可使用,确保完全兼容。

结构紧凑,仅A4纸(210 x 297mm) 大小
您可以在任何地方使用CWCA;随车携带,在野外或者实验室,使用直流或者交流供电,可选备用电池保护数据不致丢失。

 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.

 强大的分析软件

多功能分析软件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).

COM support capability enables complete control of the Compact WCA system with external application software such as Microsoft Excel.
