Just as interference testing requires an anechoic chamber, the anechoic enclosure in turn needs it's own testing. The isolation effects of shielded enclosures are only as good as their ability to prevent RF fields from extending inward or outward beyond their walled boundaries. Engineers, designers, and scientists cannot take that for granted. Below is a selection of products that we manufacture to perform shielding effectiveness testing.
Test Guide
Just as interference testing requires RF enclosures, isolation systems in turn need their own testing. This document reviews some of the issues and considerations in testing RF enclosures.

This Tech. Note covers frequently used conversion factors, how they are derived, and why they are used. If you need to convert from one series of units to another for any reason, this is the tech. note for you.
Test Guide
This test procedure describes how the small signal performance data of an amplifier is gathered and checked against previously recorded data. This is a fault finding step that establishes the health of the preamplifier.
