Reverberation chamber LUF 1GHz




A reverberation chamber is a specialized EMC test chamber generating very high field strength using modest amplifier power. The chamber is mainly used for testing electrical immunity of test objects. The shielding of the reverberation chamber model 1716-1000 is established by constructing the reverb box  from a 4mm aluminum sheet material. The outside of the test box is powder coated. The reverberation chamber model 1716-1000 creates a multi functional test box for commercial, military and automotive testing and has a Lowest Usable Frequency (LUF) of 1GHz.


Features of the reverberation chamber model 1716-1000:

  • Lowest usable frequency 1000MHz
  • Usable test volume 0.5o x 0.50 x 0.50 m (l*w*h)
  • Shielding effectiveness according to EN 50147-1 (>80dB at 10kHz)
  • Full compliance immunity test site for frequency range of 1GHz to 18GHz as per IEC 61000-4-21


Applicable standards / test methods for a reverberation chamber model 1716-1000:

  • DO-160-G
  • IEC 61000-4-21

Stirrer system for the reverberation chamber model 1716-1000

Reverberation chamber 1GHz is designed with an asymmetric triple pedal stirrer system. The pedal stirrer is vertically mounted in the reverberation box and mounted to the roof only leaving the floor of the reverberation box free for the EUT. All Comtest stirrer systems are compatible with software by Nexio, Teseq and Rohde & Schwarz. The stirrer systems can be controlled using a standard office PC or lab top. Comtest can offer the reverberation chamber as a turnkey solution incl. Nexio software, operational verification support and after sales service support.
