wavemeter การใช้

• It contains everything necessary, including an absorption wavemeter for independently measuring frequency . ]]
• During World War II, Essen worked on radar and developed a number of instruments, including the cavity resonance wavemeter.
• Activities included design, construction, and demonstration of voice-modulation equipment for a 10 cm magnetron ( July 1943 ), a microwave triode oscillator at 25 cm using cylindrical cavity resonators, equipment designed for microwave radar in field use ( wavemeter, echo box, thermistor power meter, etc . ) and microwave measurement technique.
• It provided radio components such as a Precision Variable Air Condenser ( $ 25.00 ), a Decade Resistance Box ( $ 19.00 ), a Precision Variable Inductance ( $ 24.00 ), and an Absorption Wavemeter ( $ 60.00 ), and quickly profited from strong demand for military radios during World War I and the subsequent radio broadcasting boom.
