Testing Services

Howland & Lawrence Chamber Services (The Howland Company)

RF shield testing: IEEE-299, MIL-STD-285, NSA 65-6

CTIA CATL certification testing: Probe symmetry and amplitude ripple measurements following Test Plan for Wireless Device Over-the-Air Performance

Anechoic material test, inspection, remediation: VSWR, inverse spherical nearfield testing of installed material and NRL arch screening tests of individual absorber pieces

We can also provide in-process testing of welded steel shielded enclosures with a test technique based on ASME BPVC vacuum box testing—confirm quality of RF welds before the shield envelope is complete. We developed this method for testing the Navy’s Advanced System Integration Lab (ASIL) chamber at Patuxent River, shaving weeks off the construction/testing schedule.
