S
SWITCH(1) A device used to connect, disconnect, or change the connections in an electrical circuit [1]. (2) A device used to open or close a circuit [3]. |
SWR(SWR)—The ratio of the maximum (voltage, current) to the minimum (voltage, current) points of a transmission line. Indicates the impedance matching quality of the termination of the line [10] [11]. |
SYMPTOM ELABORATIONUsing built-in indicating instruments or other aids to define equipment malfunction [16]. |
SYMPTOM RECOGNITIONRecognition of a situation in equipment operation that is not normal [16]. |
SYNCHROA small motorlike analog device that operates like a variable transformer and is used primarily for the rapid and accurate transmission of data among equipments and stations [15]. |
SYNCHRO CAPACITORA 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 [15]. |
SYNCHRO SYSTEMTwo or more synchros interconnected electrically. The system is used to transmit data among equipments and stations [15]. |
SYNCHRO TESTERA synchro receiver with a calibrated dial. This receiver is used primarily for locating defective synchros. It can also be used for zeroing synchros [15]. |
SYNCHRONIZERA circuit that supplies timing signals to other radar components [18]. |
SYNCHRONIZING NETWORKA 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 [15]. |
