WPAN /ZigBee(IEEE 802.15.4) Signal Generation Solution

Overview

The WiPAN LVSG signal generation solution is designed to generate IEEE 802.15.4 compliant signals in the 2450/868/915 MHz bands. WiPAN LVSG seamlessly integrates with the NI PXI RFSG 5670 vector signal generator. WiPAN LVSG gives full control over PHY and MAC parameters and facilitates the user to define a delay between packets with options to save and load MPDU and payload configurations (MSDU) to/from a file.

To save time and speed up the development process, WiPAN LVSG facilitates the generation of frames by customizing the MAC settings or building a sequence of frames. Customizing MAC settings can be done in three flexible options (Load MPDU data, Advanced Configuration, or Default settings). Sequences of different frames can also be generated.

WiPAN LVSG allows modeling and viewing of various impairments for simulation purposes and facilitates the viewing of key measurements with IQ plots, Eye Diagrams, Constellation diagrams (before and after pulse shaping) and a Power Spectral Density Plot.
