802.16e BS & MS 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.
