Universal Graphic Recorder Model UGR-196C
Abstract
A few of the possible applications of the UGR are to record echo soundings, seismic profiles, facsimile copies, spectral data, and to display computer generated data. The recording medium is dry electrosensitive paper. The paper roll size is 19 1/8 in. by 120 ft. with a usable scan width of 18.85 in. The viewing area is the full chart width by 12-in. long including the first printed line. Grid lines are switch selectable: 10 or 20 divisions across the chart. Line densities of 160, 128, 80, 64, and 40 lines per in. also can be selected by a switch setting. The scan mechanism is a belt with three equally spaced styluses driven by a synchronous motor. The sweep drive is generated internally by a 38.4-kHz oscillator, which makes the motor drive frequency nearly independent of power line variation. A motor frequency reference can also be supplied from an external source.
