    LAPLACELL (TEST CELLS)

    LaplaCells provide a facility for the rapid and efficient testing of the EMC compliance of products. These cells offer a calibrated and screened environment in which radiated emissions can be measured and immunity to RF radiation can be tested. They exceed the requirements of IEC61000-4-20, thus affording compliant testing to IEC61000-4-3 and pre-compliance testing for radiated emission testing.

    Laplace Instruments LaplaCell300 or LaplaCell600

    The Cells are a modified form of GTEM cell, using a balanced dual septum design which maximizes EUT volume for a given external size of cell, and dramatically improves field linearity. The EUT volume is fully lined in structural polycarbonate capable of supporting heavy products and access is via a large, full height door at the end of the cell. Adjacent to the door is the I/O filter compartment which can be customized to suit the users requirements. USB, RS232, Parallel, Ethernet, co-ax and other product specific filters can be added at time of ordering.

    Emissions Problem

    Solution

    Strong ambient signals

    The cell provides an ambient-free volume due to total screening

    Test site distortion

    The cell is fully correlated and traceable to 3m OATS

    Lack of ground plane and height scanning

    Not required!

    Lack of space

    LaplaceCells are very compact

     

    Immunity Problem

    Solution

    Expensive ancillaries

    LaplaCells include field sensors as standard

    Power amplifier requirements

    very efficient design so that RF power requirements are minimal.

    Leakage of high power RF

    Fully screened so RF energy is contained

    Field uniformity

    LaplaCell concept produces better uniformity the GTEM.

     

     

     

     

    Key Points
    · 30MHz to 3GHz or 6GHz frequency coverage

    Features
    LaplaCells are specifically intended for use by manufacturers so that they can test their own products efficiently .
    The LaplaCell design is an advance on the well known GTEM concept. However, the use of a dual septum provides:
    · better field uniformity compact external size balanced septum fed with impedance conversion network to better match OATS conditions
    · Built-in field sensor
    · Camera and lighting options
