UHFパルス発生器の試作とその妨害波測定器への応用

Abstract

妨害波測定器の比較発振器としては,CW発振器或いは二極管雑音発生器が用いられる.現在,市販の妨害波測定器の比較発振器は,ニ極管雑音発生器では出力レベルが低いという理由でCW発振器が用いられている.然しながら,このCW発生器による比較発振器は実用上周波数同調,レベル設定が繁雑であるという不便があると思われる.筆者は水銀接点リレーを用いたパルス発生器を開発し,妨害波測定器の比較発振器として満足すべき結果を得た.本論文はこのパルス発生器の原理と実験結果に関するものである.

As the comparison generator in Radio Interference and Field Intencity Measuring Equipment, a continuous wave oscillator or a vacuum tube diode noise generator had been used. At present, we do not use the diode noise generator for the comparison generator in the RI-FI Measuring Equipment in market because of the diode noise generator is low level, etc. On the other hand, the comparison generator with c-w oscillator seems to have some inconvenience ; i.e. frequency tuning and level seting are complicate for practical use. The auther developed a UHF impulse generator, utilizing a mercury-wetted contact relay, and reached very satisfied results for the comparison generator in the RI-FI Measuring Equipment. This paper is concerned with the principle and the experimental results of the Impulse Generator.
