NxGen FASS
NxGen Frequency Agile Signal Simulator
Synergent’s NxGen Frequency Agile Signal Simulator allows users to quickly and easily construct custom radar signals and digital communications signals with synthesizer-based fidelity. Based on the use of COTS test equipment, NxGen FASS is a software application to support complex microwave signal creation and sequencing. The system can be used to verify the response of receiving systems on the ground and during flight test. The system provides precision modulation and accurate output power. By providing antenna gain and amplifier gain versus frequency, the user can transmit signals with precise effective isotropic radiated power (EIRP) control.
Optional capability is available to simulate dynamic multi-emitter environments.
