Discontinued Vector and Scalar Network Analyzers

Discontinued models and series of vector and scalar network analyzers

General information

Manufacturers of measuring equipment regularly develop and put into production new models vector and scalar analyzers of electrical circuits. After some time, after the start of sales of new models, old models and series are gradually discontinued.

After the cessation of production of a particular model, we continue to support it: service and repair. As a rule, after being discontinued, factory repairs are possible for 5 years or more. After the stock of original microcircuits and spare parts in the service center is exhausted, professional factory repair becomes impossible.

Discontinued models and series of electrical network analyzers

List of discontinued models, indicating the proposed replacement, see the table below.
