Abstract

PURPOSE: To realize a high-accuracy measurement for the frequency characteristics of the cesium atomic beam tube by giving the previous adjustment to the level of the modulated wave so that the output wave level of the modulated wave may be maximum with every frequency.
CONSTITUTION: Cesium atomic beam tube M receives supply of modulated phase wave HM which received the phase modulation by modulated wave SM of the carrier featuring microwave resonant frequency ν0 plus its adjacent minimum level frequency ν+1 or ν-1 and the intermediate frequency of them. The simultaneous detection is given via analyzer 5 to output BM obtained from the M to obtain output wave QM corresponding to wave SM. Then phase rotary amount is measure based on level V of wave QM and the phase of wave SM of wave QM. In this case, the level of wave SM is adjusted previously so that the level of wave GM may be maximum with every frequency of wave SM through variation of the frequency. In this way, the frequency characteristics can be measured with a high accuracy for tube M.
