Automatic Control for the WCA300 Series and Off-line Analysis of Wireless LAN Signals

WCA11G Signal Analysis Software enhances the WCA300 Series Wireless Communications Analyzer to provide the complete evaluation of RF signals in IEEE802.11a 5 GHz, IEEE802.11b, 11g 2.4 GHz high speed wireless LAN (WCA380 up to 8 GHz: IEEE802.11a, b, g, WCA330 up to 3 GHz: IEEE802.11b, g)

The software runs on an external PC connected to the WCA300 Series over a wireline Ethernet link. The WCA11G automatically configures the WCA300 Series to acquire transmission data and transfers the results to the PC. Data is analyzed off line, where results can be easily organized, displayed, and documented.

The WCA300 Series performs real-time acquisition of signal with bandwidths of up to 30 MHz. With 30 MHz Span setting, the analyzer can capture up to 2000 Frame, which is equal 50 ms time length. The Spectrum MASK function can be used to automatically trigger an acquisition when predefined limits exceeded. Intermittent channel effects such as multi-path and transient noise can then be captured with the real-time trigger to ensure accurate analysis of the affected bursts.

Conforms with the Standards and More

The combination of WCA11G software and the WCA300 Series provides the measurements needed to ensure technical conformance with IEEE 802.11a, b, and g. Measurements that have been defined in the standards are performed in full accordance with requirements. Additional tests beyond those defined in the standards, such as spurious response and crest factor, give further insight and assurance. Instrument setups, data acquisition conditions and analysis parameters are automatically configured, eliminating set up uncertainties.

WCA11G Measurements Include:

*¹ 2.4 GHz band using with WCA330, 380.

*² 5 GHz band using with WCA380.

Share Resources in a Local Network

Because the connection to an external PC is a standard Ethernet link, shared access to the WCA300 Series can be granted to multiple stations in a lab or test facility via an Ethernet LAN. Once an acquisition is completed by one station, the WCA300 Series is free to be used by another, to capture signals directly from its own PC. With the WCA11G software, analysis and documentation are done off-line using data that has been downloaded and stored in each PC.

The WCA11G Software Can Be Run on Any Standard PC with a Minimum of:

• OS: Windows 98SE, Windows 2000, Windows XP
• CPU: Intel Pentium III, 866 MHz
• Memory: 512 MB
• Display: 1280x1024
• Ethernet LAN port
