OSCILLOGRAPH Russian patent published in 1998 - IPC

FIELD: radio measurement technology. SUBSTANCE: given oscillograph includes voltmeter 5, deviation unit 1, cathode-ray tube 2, sweep unit 3, integrator 6, stroboscopic converter 7, first 8 and second 11 delay lines and synchronization unit 4 which input is connected to synchronization bus and which output is linked to input of first delay line 8. Output of it is connected through second delay line 11, stroboscopic converter 7 and integrator 6 to voltmeter 5 and to second input of deviation unit 1. First input of the latter is connected to bus of measured signal. Output of first delay line is connected through sweep unit to first input of cathode-ray tube which second input is coupled to output of deviation unit. Oscillograph also has amplitude limiter 12. Output of deviation unit 1 is connected through amplitude limiter to second input of stroboscopic converter 7. EFFECT: improved operational characteristics. 2 dwg
