| Mobile WiMAX (IEEE 802.16e) Signal Generation Solution ( Mobile WiMAX BS and SS Receiver Testing) |
| |
| Overview |
| |
The SeaMAX Mobile BS (Base Station) IQ generator is the industries low cost solution for Mobile WiMAX equipment and chipset manufacturers, Test Houses, R&D and Academia.
SeaMAX Mobile BS IQ generator creates IEEE 802.16e compliant PHY signals required for testing the receiver functionality of Base stations.
SeaMAX Mobile BSIQ generator includes the basic and advanced features to generate WiMAX complaint signals.
The SeaMAX Mobile BS IQ signal generator creates IQ data for the Base Station. The signal generator is used to check the performance of base station receiver. It supports the DL subframe characteristics of a generated signal and creates ideal (distortion free) or impaired test signals for analysis purposes.
With the configuration options, the user can specify custom DL Burst profiles, a number of
MSs, and the impairments for the signal.
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. |
