Importance of High-Frequency SE Testing

Testing up to 40 GHz is essential for applications in:

  • Military and Aerospace: Ensuring equipment meets stringent EMI standards.
  • Telecommunications: Verifying components for 5G and satellite communications.
  • Medical Devices: Protecting sensitive equipment from high-frequency interference.

Standards for SE Testing

Several standards guide SE testing procedures:

  • IEEE 299: Standard method for measuring the effectiveness of electromagnetic shielding enclosures from 9 kHz to 40 GHz.
  • MIL-STD-285: Military standard for attenuation measurements of enclosures.
  • ASTM D4935: Test method for measuring the electromagnetic shielding effectiveness of planar materials.

Testing Procedures

SE testing typically involves:

  1. Setup: Placing the test sample between a transmitting and receiving antenna.
  2. Measurement: Recording the signal without the sample (reference) and with the sample in place.
  3. Calculation: Determining SE by comparing the two measurements.

Advanced facilities can perform these tests up to 40 GHz, ensuring comprehensive evaluation across relevant frequency ranges.

Applications of SE Testing

SE testing up to 40 GHz is applicable for:

  • Shielded enclosures and rooms
  • Electronic components and circuit boards
  • EMI gaskets and seals
  • Conductive coatings and materials

Choosing a Testing Facility

When selecting a facility for SE testing up to 40 GHz, consider:

  • Accreditation: Ensure the lab meets ISO 17025 standards.
  • Equipment: Availability of advanced testing equipment for high-frequency measurements.
  • Experience: Proven track record in SE testing across various industries.

Facilities like D.L.S. Electronic Systems offer comprehensive SE testing services up to 40 GHz.
