CRI-10CE: Immunity System

The CRI-10 Immunity System performs both radiated immunity in accordance to IEC 61000-4-3, EN 61000-4-3 and conducted immunity in accordance to IEC 61000-4-6, EN 61000-4-6 tests as required in order to affix the CE Mark. The CRI-10 Immunity System is a cost-saving solution for compliance RF immunity testing.

Features:

• Full compliance system for radiated immunity testing in the frequency range from 80 to 1000 MHz, at 10V/m.
• Full compliance system for conducted immunity testing in the frequency range from 150 kHz to 230 MHz.
• Fully automated system using software running under Windows95Ÿ.
• Software based calibration procedures.
• Failure mode for Equipment Under Test (EUT).
• Safety Interlock System protects against hazardous fields.
• Test reports available in test and graphic formats.

Benefits:

• Single rack mounted system.
• Integrated dual band amplifier optimises the use of space and budget.
• Easy expansion to higher frequencies.
• Antenna can be used for quick scan emission tests (30 - 1000 MHz)

Colour Video Monitoring System
An ideal camera system to observe the EUT behaviour during RF immunity tests. The system consists of a fibre optical remote controlled, and battery powered, color camera including a color monitor and various accessories. The system is available in PAL and NTSC format. The audio system is designed to transfer the sound, produced by EUT, located in the Test Chamber, to the operator room where it enables the operator to listen to the EUT and provide information of the correct functioning of the EUT. There are no galvanic connections because of use of a fibre optical transmission to the monitor.

Field Reference Source
The Field Reference Source is a stable, broadband reference generator. The source is designed for rapid evaluation of an EM test site and its performance. The field reference source uses a precision transmission line pulser to generate an accurate stable output.

• Frequency spacing selectable 1 MHz or 5 MHz.
• Frequency range 10 MHz - 1.5 GHz.
• Precision stable field reference.

Conducted Reference Source
The Conducted Reference Source is a stable, broadband generator. The source is designed for rapid evaluation of conducted emission measurement tools such as line Impedance Stabilisation Networks (LISN).

Shielded rooms are rooms constructed of metal (usually also having shielded doors), inside of which equipment can be tested without interference from external fields such as lightning or high-frequency (HF) radiation. An anechoic chamber is a shielded room, covered on the inside with absorbers (often Ferrite) which has a completely homogeneous field.

Shielded Rooms
The shielded rooms are mostly custom designed to meet the customer objectives in the most economical way. With the experience bundled in our team we can act as design partner and architect to the user. With our CAD/CAM design we reach the highest level of accuracy required to build high performance rooms.The rooms are constructed from 2mm hot galvanized steel plate with 2 u zinc layer. Over the years, the single layer shielding has proofed that it is maintenance free without deterioration of performance.

Semi Anechoic Chamber
A Semi Anechoic Chamber is constructed as a shielded room, with absorbing materials on all walls and ceiling, thus simulating an Open Area Test Site, without interference from environmental EM-field pollution. Its main application is in EM emission testing according to Commercial and Military standards. The floor is a full reflecting ground plane.With some additions these chambers can be used for Full Compliance Immunity testing as well. Field strengths up to 200 V/m can be generated when the necessary precautions are taken.

Compact Full Anechoic Chamber
The Compact Full Anechoic Chamber Model is used to perform compliant radiated immunity tests in accordance to EMC-standards including IEC 61000-4-3 and EN 61000-4-3.

• Full compliance immunity test site for the frequency range of 30 to 1000 MHz.
• Site attenuation deviation is ±4dB of theoretical free space transmission loss. Shielding effectiveness according to EN 50147-1 (> 60dB at 10kHz).
• Meets field uniformity specifications per IEC 61000-4-3.
• Suited for future free space emission tests, pr EN 50147-3.
• Total ferrite coverage on all planes, including full floor coverage.
• The frequency range can be extended to 18 GHz, using partial mounting of additional pyramid absorbers.
• A flush mounted, fiber optic controlled, turntable can be installed in the floor.

Comtest Shielded Swing Door
The Comtest Shielded Swing Doors are designed for high performance performance shielded enclosures. The doors can be mounted in welded EMP bunkers and in modular panel Faraday enclosures. The Shielding characteristics are achieved by use of a double beryllium copper finger contact strip. In EMC applications, ferrite tiles can be affixed to the standard door leaf. The open/close mechanism is located on the outside for ease of future access. Automatic and Semi Automatic opening and closing available.

Comtest Shielded Sliding Door
The Comtest Fully Automatic Shielded Sliding Door is designed for RF and EMP-tight enclosures. It can be integrated in Comtest Shielded Rooms as well as for other types of shielding. The standard Comtest Shielded Door is equipped with a double beryllium copper finger contact strip system. The locking and motion mechanism is based on a full electronic logic system, which can be activated from either side of the door. The door has an automatic safety feature which will stop motion if the door is obstructed.

Comtest Shielded Double Swing Doors
The Comtest Shielded Swing Doors are designed for high performance performance shielded enclosures. The doors can be mounted in welded EMP bunkers and in modular panel Faraday enclosures. The Shielding characteristics are achieved by use of a double beryllium copper finger contact strip. In EMC applications, ferrite tiles can be affixed to the standard door leaf. The open/close mechanism is located on the outside for ease of future access.
