OSCILLOGRAPH Russian patent published in 1997 - IPC

FIELD: measurement technology. SUBSTANCE: oscillograph is related to radio measurement technology. It incorporates deviation unit 1, two commutators 2,3, cathode-ray tube 4, sweep unit 5, synchronization unit 6, two stroboscopic converters 9,10 and delay line 11 which output is connected to first inputs of first 9 and second 10 stroboscopic converters. Inputs of sweep unit 5 and delay line are connected to output of synchronization unit 6 which output is connected to synchronization bus. First output of sweep unit 5 is connected to first input of second commutator 3 and to second input of second stroboscopic converter 10. Second output of sweep unit 5 is connected to second inputs of first 2 and second 3 commutators. Output of second stroboscopic converter 10 is connected to third input of second commutator 3. First and second inputs of cathode-ray tube 4 are connected correspondingly to outputs of second 3 and first commutator 2. First input of first commutator 2 and second input of first stroboscopic converter 9 are connected to output of deviation unit 1 which first input is linked to bus of measured signal. Output of first stroboscopic converter 9 is connected to third input of first commutator 2. Oscillograph also has voltmeter 12 and integrator 13 which input is connected to output of first stroboscopic converter 9. Output of integrator is connected to input of voltmeter and second input of deviation unit 1. EFFECT: increased measurement accuracy. 1 dwg
