The research methods are described and the principal characteristics of the generated oscillations are studied. We study the plasma discharge, initiated by microwave radiation with stochastically jumping phase (MWRSJP) in a coaxial waveguide at the optimal mode of the beam-plasma generator. Present results continue the line of the previous research. In this paper the plasma parameters of a microwave discharge at its stable maintenance in air by MWRSJP, and the pressure range at which required power is minimal are measured. We experimentally examine also optical characteristics of the discharge plasma in a wide range of air pressure.
