Many chambers sit inside a pit that provides space under the working floor. National and international EMC standards significantly influence chamber size, because they often specify the distance from the antenna to the EUT: 1 m, 3 m, or 10 m. For example, CISPR 22 requires a 10-m distance for EUTs larger than 2 m³ (Ref. 1).
