Discontinued Function and Arbitrary Waveform Signal Generators

General information

Manufacturers of measuring equipment regularly develop and put into production new models arbitrary signal generators and standard functions. 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 Signal Generators
