Programmable and automatic calibrator for radio sources at 45 MHz. (1981). Revista Mexicana De Astronomía Y Astrofísica, 6(1), 363-366. https://astronomia.unam.mx/journals/rmxaa/article/view/1981rmxaa...6..363a
Abstract
The design, construction and operation of a standard calibrator is presented. The calibrator consists of saturated diodes controlled by an indirect feed-back system and a digital-to-analog converter. The advantages over similar designs are described, as for instance, high-resolution in the calibration scale, good stability, very fast calibrations, use of balanced electronic switches, etc.Similar Articles
