RF LEAKAGE.....ELECTRICAL PERMITTIVITY..... MAGNETIC PERMEABILITY,

 AND SURFACE / VOLUME RESISTIVITY ...

 

1.  MEASURING RF LEAKAGE OF CONNECTORS  AND CABLE ASSEMBLIES

 

Our RF leakage test fixture is manufactured to MIL-C-39012 and is capable of measurements in excess of –100 db.    (With an appropriate analyzer).  ESS can perform the leakage for you or the fixture is available for direct sales.
	Our Rf leakage fixtures can adapt to larger diameters, long lengths and most any configuration needed for many components.

2.  MEASURING DIELECTRIC PROPERTIES  OF LOSSY AND LOW LOSS MATERIALS

 

Using our High Q cavities, we can measure complex permittivity and permeability on most microwave dielectrics.  These tests are performed per ASTM-2520.  The photos below shows both  a 3.0 GHz. and a 10.0 GHz. cavity on the left.   Our dielectric material measurement fixtures can test materials at  3 GHz, 10 GHz, 14 GHz and 30 GHz, for material property measurements.

typically used in radomes  and other resonant dielectrics...

 

  

 

 

 

3.  SURFACE AND VOLUME RESISTIVITY per ASTM D257..

The fixture shown below can measure surface and volume Resistivity of

solids, rubbers, plastics and many other electrical substrates.
