WiPAN LVSG: IEEE 802.15.4/ZigBee PHY+MAC Signal Generation Solution

 

WiLANTA LVSA11abg-Tx Testing

Overview

WiLANTA LVSA11abg is the ideal solution for research, design and evaluation of IEEE 802.11a, b and g transmitters.

WiLANTA LVSA11abg displays PHY layer measurements including raw data and MAC parameters. It allows you to take advantage of high-efficiency testing and measurements by defining suitable span, trigger, attenuation, and reference levels. WiLANTA LVSA11abg lets you analyze signal data stored on disk in .txt, .rtf, .ASCII, and .bin format. This enables importing of signal data captured elsewhere, including any third party signal generatori. Multiple .bin and .rtf signal files stored in a directory can be analyzed using WiLANTA LVSA11abgs batch processing functionality.

In addition, colorful waveforms of data along with markers and zoom options, add a third dimension to signal analysis.Its the only analyzer built to offer scalability and seamless integration with the PXI instruments.

Powerful analysis capabilities help scientists, engineers, and researchers to understand the transmitter characteristics of a WLAN DUT.

Engineers use WiLANTA LVSA11abg to create an environment that requires less cycle time to build a product with the desired attributes and performance, improve manufacturing yields, and directly contribute to overall product quality and profitability.The power of WiLANTA LVSA11abg helps you save time, money, and reduce the development risk.
