TC-5063C, Pneumatic 6 GHz TEM Cell generates the Electro-Magnetic field for testing small RF devices such as wireless communication receiver, Mobile phone, etc. An external test signal applied through the input port of the TC-5063C 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.
