OSCILLOGRAPH Russian patent published in 1997 - IPC

FIELD: radio measurement technology. SUBSTANCE: oscillograph has integrator 8, deviation unit 2, cathode-ray tube 4, sweep unit 5 and synchronization unit 7. Input of unit 7 is connected to synchronization bus and its output is linked through sweep unit 5 to first input of cathode-ray tube 4 which second input is connected to output of deviation unit 2. Output of integrator 8 is connected to second input of deviation unit which first input is connected to bus of measured signal. Oscillograph also includes commutator 3 which output is connected to input of integrator 8 and first and second inputs of commutator are connected to outputs of synchronization and deviation units correspondingly. EFFECT: enhanced operational stability and accuracy. 2 dwg
