Thermal EMI

I’m working on an article with an engineer who modified a thermal chamber to cut RF emissions when testing RF SOCs. He needed to isolate the SOC under test from the test equipment and test the device over a wide temperature range.

I’m sure that many of you have come up with clever test setups for performing EMI/RFI testing. I’ve seen some who use chicken wire to form a shielding cage and others who have built their won makeshift screen rooms. Clearly, these ad hoc test setups won’t work for compliance tests, but they can provide some degree of confidence that you’ve minimized EMI emission or immunity.

Have you come up with any ad hoc EMI/RFI/EMC test setups? I’ve like to discuss them with you. E-mail me at m.rowe@tmworld.com.
