產品介紹
CWCA，多通道型號
| CompactWCA AD-3651 
WCA AD-3651 噪音和振動分析系統（1個單元16通道采集，可擴充至4個單元64通道） | 從車輛訂單跟蹤，以MIMO技術分析
車輛實時噪音和振動分析 | | 結構緊湊，僅A4紙(210 x 297mm) 大小 24-位數模轉換器 實時倍頻程分析 通量獲取到磁盤 (標準) 支持交流、直流和備用電池 (可選) 供電 100dB 的動態范圍 多路轉速計輸入 多通路輸入輸出分析(標準) |  產品冊 (PDF 839KB) | | | | | CompactWCA |  友好的圖形界面，極易操作
以工作流程為導向的菜單可以幫助操作員減少系統設置時間，提高測試工作效率。
與WCAonPC/AD-3600完美兼容
一個兼容的用戶界面，現有的WCAonPC/AD-3600用戶無需額外培訓。此外，所有過去的數據仍然可使用，確保完全兼容。
結構緊湊，僅A4紙(210 x 297mm) 大小
您可以在任何地方使用CWCA；隨車攜帶，在野外或者實驗室，使用直流或者交流供電，可選備用電池保護數據不致丟失。
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. |  | | | | | 強大的分析軟件 | 多功能分析軟件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).
