DIGITAL STROBOSCOPIC OSCILLOGRAPH Russian patent published in 1994 - IPC

FIELD: radio measurement technology. SUBSTANCE: digital stroboscopic oscillograph has synchronization unit 1, synchronized generator 3 of trains of pulses, pulse counter 4, analog delay unit 5, former 6 of strobe pulses, stroboscopic converter 7 of studied signal, analog-to-digital converter 9, three digital-to-analog converters 11, 13, 15, first register 16, indication controller 18, processor 19, CRT 20, interface wire 10. Novelty of oscillograph lies in insertion into it of quartz generator 21, frequency multiplier 22, stroboscopic converter 23 of calibrator, two commutator 2, 8, fourth and fifth digital-to-analog converters 12 and 14 and second register 17. Period of synchronized generator 3 of train of pulses is stabilized by signal which stability is determined by quartz generator 21. This leads to realization of higher accuracy of time-base sweep of signals. EFFECT: suppression of nonlinearity of delay in unit 5 with period of synchronized generator 3 of train of pulses. 4 cl, 15 dwg
