The SeaMAX Analyzer Suite comprises of solutions that act as virtual WiMAX receivers compliant to both IEEE 802.16d-2004 and 802.16e-2005.
They are capable of demodulating the complete PHY of a received WiMAX signal and displaying its baseband characteristics for the received WiMAX frame or for individual DL/UL subframes, depending on the solution used. The demodulation is shown with a number of plots and measurements including the power spectrum, EVM, constellation (of each decoded burst), and channel frequency response. All the analyzer modules are capable of decoding the MAC data received during an acquisition and saving it to a file in hex/binary format.
The SeaMAX Analyzer Suite is offered in both offline and online (real-time) modes. The offline modules analyze IQ data captured elsewhere using a 3rd-party vector signal analyzer. The online modules are integrated with various RF vector signal analyzers to carry out real-time signal analysis in the lab or on the field. |
