3.2 Performance Test
The 6 GHz TEM Cell is a precision RF device which is built very sturdy. Their electrical
performance can, however, deteriorate with mechanical damages. Worn out shielding
gaskets, as well as metal corrosion or oxidation at the lid contact, can significantly reduce
the effectiveness of the TEM Cell. This section describes the test and calibration
procedure for the TC-5062C .
NOTE
You must performance test and verify the 6 GHz TEM Cell specifications every
time maintenance is performed on a 6 GHz TEM cell such as replacing the gasket
during routine maintenance. Also performance tests the 6 GHz TEM Cell if you
suspect mechanical damage.
