These 2~\ have been developed in the -hp- labora waveguide mounts also are non-tunable and tories for simplifying measurements of mi have a VSWR of less than 1.5. crowave power levels. These mounts have all Since thermistor mounts in themselves been designed as broadband mounts which serve only as devices for absorbing the micro require no tuning and have no tuning provi wave power to be measured, they must be sion. Any of the mounts can be used with used with a power meter such as the -hp- pulse or square-wave modulated power as Model 430B Power Meter. This meter has a well as c-w. measuring range from 0.01 to 10 milliwatts. The new mounts include both waveguide The meter itself is essentially independent and coaxial styles. The coaxial mount of frequency and can be used with any of operates over virtually the entire practical the mounts. frequency range for coaxial systems
