LogIn Crete Boosts Test Facilities

LogIn Crete based in Helsingborg, Sweden has recently expanded its operation by nearly doubling the floor area available in order to re-house its design, development and manufacturing departments. As a consequence, a major investment in test facilities has been made possible.

As a well known supplier of network communications equipment, computers and displays to the defence sector, LogIn is aware of the importance of electromagnetic compatibility (EMC), which specifies capability of electronic equipment to operate in close proximity to sources of interference, without itself emitting levels likely to cause disturbance. All of LogIn’s equipment must meet stringent EMC specifications and in order to achieve this, it is essential that both design and manufacture are monitored to ensure compliance. LogIn has installed an EMC chamber in the new facility so that the assessments to ensure compliance may be conducted in-house.

The chamber has two main compartments: a test chamber (7m x 3m x 3m) with an adjacent equipment room (5m x 3m x 2.5m) to house the sensitive test equipment required to measure and record test results. Within the test chamber a range of antennas will be used which will enable measurements to be taken between 30MHz and 18GHz. The wide-band receivers used to measure the levels of radiation are from 20Hz and 26.5Ghz.

LogIn’s customers demand that equipment complies with well known standards such as MIL-STD 461 (US) although measurements may be made to other standards such as Def Stan 59-411 (UK) if required. A typical test plan would comprise measurements of emissions, and susceptibility (radiated and conducted).

As this new EMC test equipment was commissioned, LogIn’s managing director, Tomas Odelid, said, "We are determined to stay at the forefront of the development of hardware for military electronic systems. This new in-house test facility will enable us to provide support to our design and manufacturing operation without the delays that can occur when using third-party test facilities."
