TEM CELL是宽带电场产生和辐射测量装置。TEM 单元的概念首先是由美国NBS实验室于1970年提出的,现已广泛应用于EMS和EMI测试。
当RF信号加到TEM单元内,单元内会产生近似的平面波。把被测装置放入单元内,在被测装置与平面波之间会产生电磁感应。相反, 把被测元件放在单元中,在单元输入口可测量出辐射的量值。通过测量辐射功率可推算出实际使用现场的辐射强度。

Production De
The TC-5062A, an economic UHF TEM Cell, generates a consistent Electromagnetic field for testing small RF devices such as Pagers, GPS Receivers, Phones, etc. An external test signal applied through the input port of the TC-5062A generates a consistent and predictable TEM test field inside the cell. The radiation field from a device transmitting in the Cell can also be detected through the port using a test receiver. The unique, compact and economical design is optimized for medium accuracy measurements beyond the standard TEM Cell frequency range.
