Reverberation chamber LUF 200MHz



Reverberation chambers are specialized EMC test rooms generating very high field strength using only 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. Comtest reverberation chamber creates a multi functional test environment for commercial, military and automotive testing.

The reverberation chamber model 1716-0200 has a Lowest Usable Frequency (LUF) of 200MHz. 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 1716-0200:

  • Lowest usable frequency 200MHz
  • Typical usable test volume 2.40 x 2.20 x 1.25m (l*w*h)
  • Shielding effectiveness according to EN 50147-1 (>80dB at 10kHz)
  • Full compliance immunity test site for frequency range of 200MHz to 18GHz as per IEC 61000-4-21

Stirrer system for the reverberation chamber model 1716-0200

Reverberation chamber model LUF 200MHz is designed with an asymmetric 2-pole Z-fold stirrer system. The Z-fold stirrer is vertical or horizontal mounted in the reverberation chamber. 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 serivice support.
