EM601-8 IC Stripline TEM Cell

ESDEMC’s EM601-8 is a DC to 8 GHz IC-Stripline TEM Cell that generates an electromagnetic field for testing small devices such as IC’s, wireless communication modules, etc. An external test signal applied through the input port of the EM601-8 generates a consistent and predictable TEM test field inside the cell. The radiation field from a device transmitting inside the TEM Cell can be measured 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 operating principle of EM601-8 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 measured at the input with a receiver such as a spectrum analyzer. With this method, the RF emissions from a 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
