      產品詳細介紹Product Introduction

      Redefining the test signal generator category, the Ventus 2.0 is a mobile and upgradeable system that can adapt to virtually any testing requirement while delivering unmatched value. The Ventus 2.0 can stream a transport stream, ETI and MFS (which have been captured in the field) at an industry standard 30MHz~2.7 GHz MHz RF signal output. The on-board synthesizer can generate a stable and accurate symbol clock and tuning frequency. Standing out from the pack is its list of distinguished features that equates to real value to users such as its highly versatile modular-based design, stable FPGA-based processing, USB 2.0 interface and quick modulation upgrades.

      Users can customize or upgrade the Ventus 2.0 exactly to their needs. Robust FPGA-based firmware architecture guarantees high-performance and reassuring stability even with the use of a low-performance laptop Modulation upgrades are quick and painless. The unit is not required to be shipped to the factory for service and thus saves costly downtime.
