Shield Level / Path Loss Test Equipment


PAMS-C is the essential solution for easily and efficiently making shield level measurements in commercial applications.

  • Measures signal strength shielding effectiveness
  • 864-936 MHz

  • Path loss accuracy: +/- 1 dB typ.
  • Receiver range: 0 to -120 dBm
  • Transmitter power: -30 to +30 dBm
  • Synthesized: 1 MHz and 100 kHz step size
  • Microprocessor controlled
  • AC or battery operation

PAMS-C is a simple and efficient solution for quickly identifying shielding faults in an RF shielded enclosure.  Cousin to the original PAMS used extensively by customers operating RF Shielded Enclosures, PAMS-C gives commercial end-users everything needed to measure shielding effectiveness levels of critical infrastructure - all with minimal or no interruption to normal operations. Lightweight and compact, each unit measures approximately 12" x 5" x 5" and weighs 5.5 lbs., making PAMS-C ideally suited to field measurement tasks. Rugged construction insures instrument survivability in a field test environment. PAMS-C incorporates a self-calibrating microprocessor-based architecture that provides for ease of use. It requires only minimal operator instruction for error-free operation. Its backlit LCD output displays shielding effectiveness, battery status, and other operating parameters.

A datasheet is available for this product as a PDF file.

EMI Technologies created a video which shows how they use PAMS-C to measure shielding effectiveness.  The video also demonstrates the shielding properties of different types of waveguide as well as common mistakes which will degrade shielding effectiveness.

EMI Technologies was founded in 1985 as a mechanical and electrical engineering, consulting, and fabrication services company, EMI has completed over 300 custom built vehicles. The technical staff has over 100 years combined experience in engineering design and fabrication of electronic instrumentation vans, shelters, trailers and other transportable systems.
