Reverberation chamber LUF 80MHz


 

A reverberation chamber is a specialized EMC test chamber generating very high field strength using modest amplifier power. The reverberation room is mainly used for testing electrical immunity of test objects. The shielding is established by constructing the test chamber from a 2 mm pan-type galvanized or aluminum panel system. The reverberation chamber creates a multi functional EMC test facility for commercial, military and automotive testing.


The reverberation chamber model 1716-0080 has a Lowest Usable Frequency (LUF) of 80MHz. The usable test volume depends on the size of the equipment under test (EUT) and will be determined upon customer request.


Typical features of the reverberation chamber model 1716-0080:

  • Lowest usable frequency 80MHz
  • Usable test volume 7 x 7 x 4,5 (h) m
  • Shielding effectiveness according to EN 50147-1 (>80dB at 10kHz)
  • Full compliance immunity test site for frequency range of 80MHz to 18GHz as per IEC 61000-4-21


Applicable standards / test methods for the reverberation chamber model 1716-0080:

  • IEC 61000-4-21
  • MIL-STD-461-E&F
  • RTCA/DO-160-G
  • EUROCAE/ED-14F

In addition to our standardized models all chambers are available in customized dimensions to satisfy our customers’ individual requirements.

Reverberation chamber 80MHz is designed with an oscillating wall stirrer. This innovative stirrer design is invented by Comtest Engineering and is a patented design. The new and innovative stirrer design achieves higher field strengths and a larger test volume inside the reverberation room.  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 and after sales service support.
