S
SATELLITE ECLIPSEAn eclipse where the rays of the sun do not reach the satellite. This prevents recharging of the solar cells of the satellite and decreases the power to the transmitter [17]. |
SATELLITE-SUN CONJUNCTIONA period when the satellite and sun are close together and the noise from the sun prevents or hampers communications [17]. |
SATURABLE-CORE REACTORA coil in which the reactance is controlled by changing the permeability of the core [8]. |
SATURATION(1) The condition existing in any circuit in which an increase in the input signal produces no further change in the output [13]. (2) The operating point of a vacuum tube or transistor at which a further increase in grid or base current no longer produces an increase in plate or collector current [6] [7]. (3) In a magnetic core, the condition in which a magnetic material has reached a maximum flux density and the permeability has decreased to a value of (approximately) 1 [8]. |
SCALING FACTORThe term used to describe the use of unequal resistors in a servo's summing network to compensate for differences between input and output signal levels [15]. |
SCANNING(1) The process of subdividing a picture in an orderly manner into segments. This is used in facsimile transmission [17]. (2) Systematic movement of a radar beam to cover a definite pattern or area in space [18]. |
SCAT CODEA four-digit subcategory code used to identify the functional measurement parameters that can be satisfied by any one of many pieces of test equipment [16]. |
SCATTER ANGLEThe angle at which the receiving antenna must be aimed to capture the scattered energy of tropospheric scatter [10]. |
SCHEMATICA diagram which shows, by means of graphic symbols, the electrical connections and functions of a specific circuit arrangement [1] [4]. |
SCHEMATIC SYMBOLSA letter, abbreviation, or design used to represent specific characteristics or components on a schematic diagram [1]. |
