Abstract To describe testing techniques for a hydrogen maser,these techniques are important for operating point setting and optimal operating condition keeping as well as for understanding and calculating of long-term frequency behavior of a hydrogen maser during its operation, especially long period of operation.The methods which are for producing and processing of a maser “baseline” data are also presented.
