Test Cells

Test cells (LaplaCell)

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.

The Cells are a modified form of GTEM cell, using a balanced dual septum design which maximises 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 customised to suit the users requirements. USB, RS232, Parallel, Ethernet, co-ax and other product specific filters can be added at time of ordering.

Key Points

  • 30MHz to 6GHz frequency coverage
  • Fully calibrated for emissions and immunity
  • 2 sizes:
  • Lc300:  for EUT up to 30cm cube
  • Lc600:  for EUT up to 60cm cube (incl. 19" racks up to 13u)
  • Field sensor for immunity testing is included
  • Calibrated in accordance with IEC61000-4-20
  • Excellent field uniformity
  • Compact size
  • Ready for immediate use on delivery
  • Standard filtered I/O includes mains feed, fibre optic access and 12 individual connections.
  • LC300_image_2


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
