Part Details | ELECTRONIC MARKER GENERATOR
5895-00-556-0818 An electronic device which generates electrical pulses of precise characteristics with respect to amplitude, shape, duration and recurrence. Such pulses serve as reference indices on the screen of a cathode ray tube for determination of data such as radar target range, azimuth, elevation and similar applications. See also GENERATOR, SIGNAL and GENERATOR, PULSE.
