C1 provides fine frequency control of 5-Mc primary frequency standard, when driven by 100-cps control signctl from cesium beam tube.This will change frequency up to 2.5 cps,sufficient for short-lime drifts over several days. When C1 reaches either end of its range, cam doses s1 or s2 and energizes drive motor M1 for C2. Lorge capacitor is then driven in direction that will make small capacitor return to middle of its range.-W.A. Mainberger, Primary Frequency Standard Using Resonant Cesium, Electronics, 31:45, p80-85.
