BS EN 61326-2-1 includes more detailed test configurations, operational conditions and performance criteria for equipment with test and measurement circuits (both internal and/or external to the equipment) that are not EMC protected for operational and/or functional reasons, as specified by the manufacturer.
The manufacturer specifies the environment for which the product is intended to be used and/or selects the appropriate test level specifications of IEC 61326-1.
Examples of equipment include, but are not limited to, oscilloscopes, logic analysers, spectrum analysers, network analysers, digital multimeters (DMM) and board test systems.
BS EN 61326-2-1:2006 partially supersedes BS EN 61326:1998 which will be withdrawn on publication of BS EN 61326-1:2006 and all of the parts of the BS EN 61326-2 series of standards (BS EN 61326-2-2:2006, BS EN 61326-2-3, BS EN 61326-2-4, BS EN 61326-2-5 and BS EN 61326-2-6:2006).
