| IQ Generator |
| |
| Overview |
| |
The software creates a baseband I/Q waveform file based on the user-defined 802.11a/b/g settings and saves the signal files in .txt format on the computer’s local hard drive or any other specified location. In addition to creating ideal waveform files with or without a MAC configuration, the software provides configurations to create and save impaired signal.
WiLANTA IQ generator simplifies the 802.11a/b/g test signals by providing an intuitive graphical user interface which enables the user to quickly configure a standard based test signal with complete control over MAC Frame data.
WiLANTA IQ generator creates all supported 802.11b/g MAC Frames (Data, Management and Control) including the sub frames mentioned in the standard, and saves this information in .txt format.
WiLANTA IQ generator allows designers/engineers to accurately create and save ideal or impaired signals. The signal files can be downloaded to WiLANTA LVSA11bg signal analyzer or any other third party analyzer or generator. |
