A plasma instrument (called PIMS) sensor assembly is subjected to a simulated electromagnetic interference (EMI) environment to ensure it will function correctly in space while telecommunications equipment and radar instruments aboard the spacecraft operate. The PIMS sensor assembly is placed inside a plastic box to keep it clean and free of biological contamination. This test took place in the anechoic chamber at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland. The chamber is specifically designed to test for simulated EMI and blocks outside RF signals such as cell phone signals and Wi-Fi.
