BREAKIn a switch, the number of breaks refers to the number of points at which the switch opens the circuit; for example, single break and double break [3]. |
BREAKDOWNThe phenomenon occurring in a reverse-biased semiconductor diode. The start of the phenomenon is observed as a transition from a high dynamic resistance to one of substantially lower dynamic resistance. This is done to boost the reverse current [7]. |
BRIGHTNESS CONTROLThe name given to the potentiometer used to vary the potential applied to the control grid of a CRT [6]. |
BROADSIDE ARRAYAn array in which the direction of maximum radiation is perpendicular to the plane containing the elements [10] [18]. |
BRUSHESSliding contacts, usually carbon, that make electrical connection to the rotating part of a motor or generator [5]. |
BUFFERA voltage amplifier used between the oscillator and power amplifier [12]. |
BUFFER AMPLIFIERAn amplifier that isolates one circuit from another. It decreases the loading effect on an oscillator by reducing the interaction between the load and the oscillator [9] [18]. |
BUILT-IN TEST EQUIPMENT (BITE)A permanently mounted device that is used expressly for testing an equipment or system [14]. |
BUNCHER CAVITYThe input resonant cavity in a conventional klystron oscillator [11]. |
BUNCHER GRIDIn a velocity-modulated tube, the grid that concentrates the electrons in the electron beam into bunches [11]. |
