Please join the AAAA Jersey Chapter for an in-person and virtual Lunch and Learn on Tuesday, March 5th! Mr. Duncan Dhemecourt, Application Engineer and Mr. Bill Kardine, Radar/EW Business Development Manager of Rohde & Schwarz will present from the EW Environmental Generation Engineering Series.  The presentation series covers common engineering and design challenges necessary to understand the problem of simulating an electromagnetic environment for testing EW devices. The next generation of EW devices and platforms bring new difficulties: modern threats get faster, more agile, and more complex. The testing challenges for our friendly devices scale accordingly.

This presentation frames complex problems faced by test engineers as they consider various solutions and design trade-offs in present and future environmental generation test challenges. Taking a bottom-up approach, discussions will cover the conversion chain from the digital backend EW scenario generation interface through the analog RF output.

Topics will include:

? pulse descriptor word fundamentals

? RF emitter bandwidth, frequency, and level considerations

? multiple RF port system architectures

? alignment of multiple RF ports in time, level, and phase

? phase locking a multi-port RF system
