802.16d BS & SS Receiver
Testing |
Overview
SeaMAX IQ Generator Pro designed to generate ideal/impaired IEEE
802.16-2004 OFDM PHY compliant RF signals in real time. The software
also creates baseband I/Q waveform file based on the user-defined Base
Station (BS) and Subscriber Stations (SSs) settings and saves the
signal files in .txt format on computer’s local hard drive or any
other specified location.
The generator provides functionality to create WiMAX TDD frame with
user configurable downlink and uplink bursts. It provides an intuitive
graphical user interface to configure uplink and downlink waveforms,
CP, BW and Frame length as per standard specifications.
To verify receiver robustness, SeaMAX IQ generator Pro provides
various additive impairments which can be added to the test signal and
the configuration can be saved in .txt format. These signal files can
be downloaded to AWG for IF/RF signal generation or SeaMAX Fixed IQ
Analyzer Pro/Third party analyzer for analysis.
SeaMAX IQ generator allows WiMAX equipment manufacturers, chipset
developers, designers and RF engineers to test both subscriber and
base station’s receiver functionality throughout the development phase
of their products.
Easily create signals to evaluate the performance of your radio
designs, and the components that comprise them, under various
parametric and functional test conditions at baseband, RF and
microwave frequencies.
