Functions

The decoder can be used in different configurations:

• Local use in a PC with standard W61PC application software.
• Remote use over a LAN with standard W61PC application software.
• Remote control from other applications using third party software, e.g. Radio Monitoring Tools, Alarm Monitor.

This allows the system to be adapted to the client's need and applications.

Using an audio or IF input signal, the W61PC decodes a variety of text and graphical transmission modes. The determination of signal characteristics is assisted by a large number of analysis and measurement functions operating over a wide range of signal parameters. The W61PC is the advanced next-generation decoder in the well known WAVECOM line of decoders. The W61PC is equipped with powerful DSP software and hardware to allow the realization of real-time demodulators and filters. The large onboard memory provides sufficient space for data buffering. Additionally, the whole computing power of the host PC is also available for data processing.

The application utilizes TCP/IP to communicate with other W61PC cards available on the LAN. A maximum of eight W61PC cards may be installed into one PC, providing the basis for a high performance signal decoding system. This, combined with the network capabilities, allows a system to be set-up for many different configurations. Complex systems for massive data processing, are only limited by the number of cards and the performance of the hardware and software.

The configuration of the system components can be completely adapted to the requirements of the customers. A W61PC decoder card may be controlled from everywhere in the network, and its output may be sent to one or more applications on the network. Any PC can be used for remote control of W61PC cards for decoding, storage, analysis and monitoring.

The W61PC software is a 32-bit Microsoft Windows application providing a familiar user interface and system functions. The availability of sophisticated software development tools allows rapid implementation of new functionality. In order to process the data output, control the hardware and the code parameters of the W61PC, a remote control interface is available, allowing easy integration between the W61PC and customer applications. The easy-to-use user interface with well structured pull-down menus allows an operator to become familiar with the W61PC in a short time. A high degree of operator proficiency can quickly be achieved.

All of the integrated analysis tools contain many different methods and viewing options. They assist the operator in analyzing the important signal parameters. Exact measurements are easily made using adjustable cursors with associated numerical displays. Dynamic zoom functions allow magnification of details in any selected window. The scroll buffering feature makes it possible to move back and forward in signal history. Real-time FFT functions with a fast display refresh rate are implemented. Additional powerful functions provide the tools for analyzing unknown signals. A wide range of system default settings can be configured, e.g. input signal level, sampling rate, measuring interval, centre frequency and demodulator type. Additionally, a variety of international alphabets can be selected.
More than 150 modes are currently implemented.
