OSCILLOGRAPH Russian patent published in 1997 - IPC

FIELD: radio measurement technology. SUBSTANCE: proposed oscillograph incorporates voltmeter 5, deviation unit 1, cathode-ray tube 2, sweep unit 3, integrator 6, stroboscopic converter 4, delay line 8 and synchronization unit 7. Input of unit 7 is connected to synchronization bus and sweep unit 3. First and second inputs of stroboscopic converter 4 are connected correspondingly to outputs of delay line and deviation unit. First input of deviation unit is connected to bus of measured signal, outputs of sweep unit 3 and deviation unit 1 are connected correspondingly to first and second inputs of cathode-ray tube. Input of voltmeter 5 and second input of deviation unit 1 are connected to output of integrator 6. Oscillograph is inserted with attenuator 11. Output of stroboscopic converter 4 is connected to input of integrator 6 via attenuator. EFFECT: increased operational accuracy. 4 dwg
