2500B Series Microwave Signal Generator Specifications formally describe product performance. A specification is a numerical value, or range of values, that bounds the performance of a product parameter. The product warranty covers the performance of parameters described by specifications. Products meet all specifications when shipped from the factory. Typical and Nominal describe product performance that is useful in the application of the product, but is not covered by the product warranty. They describe performance that is expected of a given product at room temperature after 30 minutes...
