EM602-10 Mini TEM Cell (DC-10 GHz, 1kV)

ESDEMC’s EM602-10 is a 10 GHz Mini TEM Cell generates very strong electromagnetic field for testing small devices such as sensors, IC’s, wireless communication modules, etc. An external test signal applied through the input port of the TEM cell 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.

Features:

  • Up to 10 GHz bandwidth (Beyond normal TEM Cell bandwidth of 3 GHz)
  • Can inject up to 20 kV/m E-field for sensor EM Field Susceptibility

Description

1.    Description

ESDEMC’s EM602-10 is a 10 GHz Mini TEM Cell generates a very strong electromagnetic field for testing small devices such as sensors, IC’s, wireless communication modules, etc. An external test signal applied through the input port of the TEM cell 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 design is optimized for a very strong electromagnetic field injection test beyond the standard TEM Cell in both field strength and frequency range. 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 the 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. The EM602 TEM Cell requires 40W input power to achieve > 20 kV/m RMS E-field or > 80 A/m RMS H-field. It is recommended that the test PCB have metal-plated edges for better shielding.
