Shielded Bulkhead Connectors Mitigate Ambient Emissions for Military & Avionic EMC Testing

Most Military/Avionic EMC test programs include radiated emissions testing.  This is the test method where the unintentional emissions which    radiate from a piece of electronic equipment under test are measured with an antenna and spectrum analyzer and plotted against the required limit.  One issue which must always be dealt with during radiated emissions and...

RF Survey Assures Wireless Connectivity

MET Labs recently completed a novel RF survey for a large federal government agency laboratory, to determine whether refrigerators and freezers on multiple floors in multiple buildings are receiving a sufficient-strength wireless signal with minimal noise. Here are some of the project details, as well as surveyed information: Operating frequencies: 2.4 GHz ISM Band; 5... Read More
