Reverberation chamber LUF 400MHz

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

The reverberation chamber model 1716-0400 has a Lowest Usable Frequency (LUF) of 400MHz. 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 1716-0400:

  • Lowest usable frequency 400MHz
  • Typical usable test volume 0.80 x 0.80 x 0.80 m (l*w*h)
  • Shielding effectiveness according to EN 50147-1 (>80dB at 10kHz)
  • Full compliance immunity test site for frequency range of 400MHz to 18GHz as per IEC 61000-4-21
