5 EC Declaration of Conformity We Tektronix Holland N.V. Marktweg 73A 8444 AB Heerenveen The Netherlands declare under sole responsibility that the VX4750 Option 04 meets the intent of Directive 89/336/EEC for Electromagnetic Compatibility. Compliance was demonstrated to the following specifications as listed in the Official Journal of the European Communities: EN Class A Radiated and Conducted Emissions EN Emissions: EN AC Power Line Harmonic Emissions EN Immunity: IEC Electrostatic Discharge Immunity IEC RF Electromagnetic Field Immunity IEC Electrical Fast Transient/Burst Immunity IEC Power Line Surge Immunity To ensure compliance with EMC requirements this module must be installed in a mainframe that has backplane shields installed that comply with Rule B.7.45 of the VXIbus Specification. Only high quality shielded cables having a reliable, continuous outer shield (braid & foil) that has low impedance connections to shielded connector housings at both ends should be connected to this product. Additionally, any cable attached to the S3 or S4 connector must pass through a ferrite block while making at least one complete turn. Use a Steward PN 28B ferrite block or equivalent. The ferrite blocks should be mounted as close as possible to the connectors on the VX4750.
