11/13/2002 - Agilent Technologies introduced the industry's most comprehensive array of software-based modulation analysis and troubleshooting tools for designers of 802.11g wireless LAN (WLAN)-compatible transceivers and components.
These enhancements to the Agilent 89600 series vector signal analyzers (VSAs) are among the first analysis tools available to designers of 802.11g components. When combined with Agilent's existing 89600-based 802.11a and 802.11b analysis tools, the new software completes one of the most comprehensive suites available for analyzing the complex signals of all current and proposed WLAN standards — 802.11a, 802.11b, and 802.11g.
Agilent also released enhanced capabilities for its 89600 VSA 802.11a and 802.11b WLAN software solutions, including a separate "one-button" 802.11 test application.
Agilent is also introducing the 802.11g WLAN Signal Studio software for the E4438C ESG vector signal generator. This product complements the company's existing 802.11a and 802.11b WLAN Signal Studio waveform generation software, which can be downloaded directly from the Agilent Web site for evaluation. License keys purchased from Agilent are required in the ESG signal generator to download the 802.11 WLAN test signals from the Signal Studio software to the ESG.
Complete Analysis Flexibility
The new 802.11g software for the 89600 series VSA has all of the features of the current 802.11a and 802.11b software. These include the ability to demodulate WLAN bursts to the bit level; a compound constellation display to automatically determine and display all modulation formats present in the signal; and the ability to evaluate modulation quality using error vector magnitude (EVM) displays of the overall burst, each symbol, or each subcarrier in a symbol.
New 802.11g-specific features include automatic detection, demodulation, and despreading of the four mandatory 802.11b signal formats (1, 2, 5.5, and 11 MHz) as well as detection and decoding of the optional 802.11b and 802.11g PBCC (packet binary convolutional code) formats. The software will also detect the optional CCK-OFDM (complementary code-keying-orthogonal frequency division multiplexing) format and automatically detect, demodulate, despread, and descramble the standard 802.11b preamble and short 802.11b preamble (optional in the standard) to determine the expected burst length and modulation type.
Enhancements to 802.11a analysis include the ability to skip over the 802.11g CCK-OFDM payload and demodulate the 802.11a-compatible data payload. The new "one-button" 802.11a test application allows quick and easy standards-based testing on 802.11a signals.
New 802.11g Capabilities for Signal Studio
The 802.11g WLAN Signal Studio software for the E4438C ESG vector signal generator provides a quick and easy way to create test signals for 802.11g component or receiver tests. For component testing, the software enables users to determine the performance characteristics of 802.11g WLAN components and to modify signal parameters to meet customized test needs. In addition, the software can generate statistically correct signals to properly stress components. For receiver testing, the software creates fully coded 802.11g WLAN frames, which enables FER, PER, and BER receiver sensitivity testing and allows demodulation capability of 802.11g WLAN receivers to be verified.
U.S. Pricing and Availability
The Agilent 89600 vector signal analyzers are available now and range in price from $35,000 to $70,000. The 802.11g analysis tools, which will be included in the WLAN Option B7R for the 89600 VSA, are expected to be available in December 2002 at prices below $6,000. The E4438C vector signal generator is available now starting at $17,353. The 802.11g WLAN Signal Studio software is available now at a price of $5,500 or less, depending on previously purchased WLAN Signal Studio license keys.
