ETS-Lindgren's Universal Spherical Dipole Source (USDS) is an instrument that helps you maintain the integrity of your test environment (chamber or OATS). It does this by allowing you to create a radiated emissions profiles that can be compared with other profiles made on a daily basis. Differences in profiles can indicate changes occurring in the test environment that may affect the accuracy and repeatability of test results.

For example, deteriorating cable shielding or weakening chamber seals may go unnoticed, but result in a loss of measurement integrity. By taking daily measurements with the USDS and comparing profile results, these changes become known and can be investigated and corrected.

Test environments can be characterized using complex published methods, but the USDS provides a quick, convenient method that makes daily measurement practical and affordable.
