ODS–3000 Analog Fiber Optic Data acquisition System

This recent addition to the ODS range of EMP/EMC links extends the operating bandwidth to 3GHz whilst still retaining many of the important functional features of the new ODS–2200.   The ODS–3000 is specifically designed to meet the requirements of the industrial RF immunity testing standards included in EMC Directive 2004/108/EC, in addition to many other wideband EMP/EMC testing requirements.
