NU Labs is equipped with two shielded enclosures to provide electromagnetic
interference testing required by current Military specifications. The first is a Panashield semi-anechoic electromagnetic shielded enclosure.  It has an inside dimension of 23' x 16' x 12' with a usable test area of 9.8' x 8'.  The chamber uses 20" carbon impregnated cone material for RF absorption and conforms to MIL-STD461E/F.

The second chamber, a Universal Shielding Corp. shielded enclosure, measures 12' x 9' x 9' and has a entry door that is 35.5" wide by 84" high.  All power to both chamber is filtered.   

We provide testing and engineering services from full engineering evaluation to full qualification tests.  NU Laboratories can aid in troubleshooting as well as provide solution engineering for EMI/EMC problems and test failures.
