Modular Enclosures Help Certify Resistance to Electromagnetic Interference

One way to minimize hassles when certifying properties such as resistance to electromagnetic interference is to use predictable and well-understood components. This was the approach taken by Luna Technologies, Blacksburg, Va., for its optical-vector analyzers. The analyzers characterize signals of optical components and must pass stringent EMI and RFI-compliance regimes. The company uses a Type-32 enclosure from Elma Bustronic Corp., Fremont, Calif., which gives customers several shielding options. The design is standard in the 2U and 4U sizes that Luna needed. A modular design lets the enclosures easily change to other heights, widths, and depths, and Elma also custom paints or powder-coats them and applies digital printing for customers.
