Compact WCA AD-3651 System Configuration
In-vehicle Real-Time Noise and Vibration analysis system
System Configurations
The CWCA is a compact A4 size unit for in-vehicle real-time noise and vibration analysis.

The Compact WCA system is scalable from 4, 8 to 16 channels in a single A4 size front-end. Expansion to a 32-ch, 48-ch or 64-ch configuration is possible using a synchronized connection of several front-ends.

The front-end hardware is connected to a PC via LAN (100Base-T).
Vehicle installation kit
The CWCA supports real-time in-vehicle vibration/ noise analysis with an in-vehicle kit equipped with a backup battery. Power supply is available from the vehicle's cigarette lighter socket by inserting the attached plug. The cigarette lighter plug is included in this vehicle installation kit, so a power supply is available for a laptop computer (Power plus for laptop PC is required separately.) . This in-vehicle kit can be integrated with the rear panel side of Compact WCA. If you purchase an in-vehicle remote-control keypad, you can control the starting or stopping of data acquisition using a Windows PC.
Throughput to Disk function
Time history data can be copied to the hard disk of the PC for playback analyses. Off-line analysis on a standalone PC is also available with an off-line license. The recorded throughput data can be exported in WAV format.

Off-line analysis (Optional)
Off-line analysis using a standalone PC is also available with an off-line license. FFT analysis, tracking analysis, real-time octave analysis and time-series filter processing are available for time-series data, which is recorded using the throughput function. The CWCA also supports times-series data from data recorders, manufactured by other analyzer vendors.
In addition, a layered display with the analyzed data file (MFU file), a value reading using the cursor function and 2D/3D post processing calculation are available.
Flexible Menu Customization with COM support
WCAPRO can be controlled through COM interface from VB or VBA.
The user can customize the screen using the COM function for typical processes and repeated operation.
In the case of recalling typical conditions and repeating data collection, FFT analysis and tracking analysis are available with a simple 6-button operation as you can see below. A&D supplies free samples of COM programming for this purpose.
