Simulation parameters

Multi-emitter simulation

Multiple emitters are played from a PDW list according to the capability of the UXG to transition

frequency and amplitude according to the number of emitters and their duty cycles

Multi-UXG

Connect to multiple UXGs to increase pulse density and simulate AoA; angle-of-arrival or multi-channel

calibration is provided

Emitter interleaving

Emitters are interleaved to optimize pulse density and minimize dropped pulses while maintaining

accurate pulse width and PRI

Dropped pulse reporting and pulse collision

reporting

Pulse collision percentages and conflicting emitters are reported; modifications to emitter start

time and priority can be made in the report to resolve conflicts; report is recalculated when emitter

parameters are changed

Scenarios

Create a hierarchy of platforms, emitters, modes, and waveforms; user can build up a library of emitters

or modes and reuse them in different simulations

Test system definition

Add one or more UXG agile signal generators with different options to the simulation

System under test definition

Set the minimum simulation power level according to the sensitivity of the receiver under test
