EM603-8 IC Stripline TEM Cell (DC-8 GHz, up to 1 kV)

ESDEMC’s EM603-8 is an 8 GHz IC Stripline TEM Cell generates the Electro-Magnetic field for testing small devices such as IC’s, wireless communication modules, etc. An external test signal applied through the input port of the EM603-8 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. The operation principle of EM603-8 is essentially the same as TEM Cell. The E-H field inside the test volume is proportional to the input voltage and inversely proportional to the cell height. If a radiating object is inserted inside the cell, the radiated wave toward input port is guided by the transmission line and picked up at the input with a receiver such as a spectrum analyzer. With this method, the RFI from a radiating device can be measured quantitatively. Since this apparatus is very broadband, it has many applications in the area of EMI, EMS, receiver sensitivity test, etc.

Features

  • Up to 8 GHz bandwidth (beyond normal TEM Cell bandwidth of 1 GHz)
  • Can test up to 1 kV high voltage for field injection
