Abstract: A theory for fast modulation effects in cesium frequency standards has been developed and expressions derived for frequency offsets produced by Rabi and cavity pulling with square wave phase modulation. These are compared with equivalent expressions for sine-wave phase modulation. Ratios of the amplitudes of the frequency offsets in the two modulation schemes are calculated for a mono-velocity beam and shown to be in agreement with measurements performed on a commercial standard. This analysis allows a more complete evaluation and comparison of different modulation schemes for cesium atomic beam standards.
