Previous set of "S" terms and definition.
SYMMETRICAL MULTIVIBRATOR. A circuit that generates square waves.
SYNCHRO. A small motor-like analog device that operates like a variable transformer and is used
primarily for the rapid and accurate transmission of data among equipments and stations.

SYNCHRO CAPACITOR. A unit containing three delta-connected capacitors. The synchro capacitor is used in synchro systems to increase the system’s accuracy by cancelling or reducing the phase shift introduced by synchro inductance.
SYNCHRONIZER. A clocking circuit that supplies timing pulses to another circuit. A circuit that supplies timing signals to other radar components.
SYNCHRONIZING NETWORK. A circuit, also called a crossover or switching network, used in servosystems to sense how far the load is from the point of correspondence; it then functions to switch the appropriate signal into control.
SYNCHRONOUS. One or more circuits operating under the same clock relationship.
SYNCHRONOUS MOTOR. An ac motor whose rotor is activated by dc. It is characterized by constant speed and requires squirrel-cage windings or some other method to be self-starting. [Motor Manufacturers]
SYNCHRONOUS ORBIT. An orbit in which the satellite moves or rotates at the same speed as the earth.
SYNCHRONOUS SPEED. The speed at which the rotating field in an ac motor revolves. This speed is a function of the number of poles in the field and the frequency of the applied voltage.
SYNCHRONOUS TUNING. In a klystron amplifier, a method of tuning that tunes all the resonant cavities to the same frequency. High gain is achieved, but the bandwidth is narrow.
SYNCHRO SYSTEM. Two or more synchros interconnected electrically. The system is used to transmit data among equipments and stations.
SYNCHRO TESTER. A synchro receiver with a calibrated dial. This receiver is used primarily for locating defective synchros. It can also be used for zeroing synchros.
SYSTEM. A combination of sets, units, assemblies, sub-assemblies, and parts joined together to form a specific operational function or several functions.
