To satisfy each unique customer requirement Comtest Engineering can provide turnkey solutions for the following EMC test facilities:
– SAC 3m, 5m 10m
– MIL STD, CISPR 25
– antenna FAR
Features of a typical semi anechoic chamber:
– full compliance emission test site for frequency range of 30MHz to 18GHz as per CISPR 16-1-4
– full compliance immunity test site for frequency range of 80MHz to 6GHz as per IEC/EN 61000-4-3
– shielding effectiveness according to EN 50147-1 up to 40GH
Comtest reverb rooms comply with the IEC 61000-4-21prt 4-21, EUROCAE/ED-14F, MIL-STD 461F, RTCA/DO-160F and various automotive standards. They are offered with traditional stirrer system or with an oscillating wall stirrer. All Comtest stirrer systems are compatible with software by Nexio, Teseq, R&S or Raditeq. Depending on the measuring frequency range, the following sizes of the working areas of the chamber are available:
– 80MHz–18GHz EUT: 7 x 7 x 4m (h)
– 100MHz-18GHz EUT: 5 x 5 x 3.5m (h)
– 200MHz-18GHz EUT: 2.2 x 2.4 x 1.25m(h)
– 400MHz-18GHz EUT: 0.8 x 0.8 x 0.8m (h)
– 1000MHz-18GHz EUT: 0.5 x 0.5 x 0.5m (h)
The application of Comtest RF shielded rooms provides high performance shielding effectiveness up to 40 GHz according to EN50147-1. The Comtest RF shielded doors are designed for high performance shielded enclosures. The shielding characteristics are achieved using a double knife edge, matching quadruple beryllium copper finger contact strip. Comtest RF shielded doors are equipped with a unique parallel closing mechanism and patented locking and latching system. All the RF shielded doors can be delivered in manual, semi- and full automatic operation. Depending on the finish of the Faraday cages, with the use of appropriate filters and media converters, they can be used as RF shielded data center, MER (Main Equipment Rooms), conference rooms and crisis control centers or RF shielded control and amplifier rooms.

All of our absorbers are high performance polystyrene microwave absorbers suited for all anechoic chambers. The product range includes both hybrid (EMC) and microwave (broadband) absorbers. These absorbers are sustainable and 100% environmentally friendly. As a result the absorbers are fully compliant with REACH and ROHS.
The hybrid absorbers: HT25 (10”), HT45 (18”), HT65 (26”)
The microwave absorbers: MT25 (250mm/10”), MT45 (450mm/18”), MT65 (650mm/26”), MT105 (1050mm/41”)
Hybrid plates Ferrite (sintered metallic ceramic materials with ferromagnetic properties) provide excellent electromagnetic absorption performance at frequencies from 20MHz to 1GHz. They are widely used in the EMC and EMI chambers. Ferrite tiles may be mounted directly – affixed to the housing of a shielded room or screwed to the internal structure of the chamber. Standard dimensions of the ferrite tile are 100x100x6mm.
