The U.S. Army White Sands Missile Range (WSMR) Electromagnetic Radiation Effects (EMRE) facility is one of the largest Open Air Tests (OATS) facilities in the USA. The facility provides full body illumination testing of large vehicle systems. Many large test items come to EMRE every year to conduct their mandatory Electromagnetic Environmental Effects (E3) testing.

The EMRE required an ARB that would provide broadband signals up to 20 GHz, 50 GSa/s with all the latest modulations that the DoD has used over the past 7 years. This ARB would also add the ability to generate signals specific to the test item so that much more thorough evaluation of item performance could be achieved.
