OSCILLOSCOPE Russian patent published in 1995 - IPC

FIELD: radio measurement technology. SUBSTANCE: oscilloscope has two switches 2, 3, cathode-ray tube 4, stroboscopic converters 9, 10, voltmeter 12, sweep unit 5, deflection unit 1, delay line 11, and synchronizing unit 6 whose output is connected through delay line 11 and first stroboscopic converter 9 to input of voltmeter 12; synchronizing bus is connected through synchronizing unit, sweep unit, and second switch to first input of cathode-ray tube; measured signal bus is connected through deflection unit and first switch to second input of cathode-ray tube; second output of sweep unit is connected to second inputs of two switches; deflection unit output is connected to second input of first stroboscopic converter whose output is connected to third input of first switch; delay line output is connected to first input of second stroboscopic converter. Oscilloscope is also provided with subtracting unit 14 and integrator 13; first output of sweep unit 5 is connected through subtracting unit 14 to second input of second stroboscopic converter 10 whose output is connected through integrator 13 to third of second switch 3 and to second input of subtracting unit 14. EFFECT: improved accuracy of matching of brightness mark and oscillogram, improved measurement accuracy, reduced complications and labour consumption for making measurements. 1 dwg
