MULTICHANNEL RECORDER Russian patent published in 1994 - IPC

FIELD: instrumentation engineering, particular, electrical measurement equipment. SUBSTANCE: multichannel recorder has clock pulse generator, multichannel A/D converter with normalizers at inputs, control pulse shaper of normalizers connected with its output to control inputs of normalizers, and data receiver, as well as counter-divider, memory and synchronizing unit, whose sync input is connected with dividing output of counter-divider, whose input is connected to output of clock pulse generator and input of starting the A/D converter and with counting output to control input of A/D converter whose output is connected with information input of memory whose output is connected with input of record control; input of record control is connected with converter output of A/D converter, sync input with divider output or with counter output of counter-divider and control input with gating output of data receiver whose control input is connected with output of synchronizing unit. Input of normalizer control pulse shaper is connected to divider output or counter output of counter-divider. Synchronizing unit is made in form of univibrator whose input and output serve as sync input and output of readiness of synchronizing unit, respectively. Synchronizing unit is made in form of R-S flip-flop whose S and R inputs and output serve as sync input, input of readiness reset and output of readiness of synchronizing unit, respectively. In this case input of readiness reset is connected with gating output of data receiver. Synchronizing unit is made in form of D flip-flop whose S, C and R inputs and output serve as sync input, additional sync input, input of readiness reset and output of readiness of synchronizing unit respectively. In this case, input D of flip-flop is connected with busbar of zero signal and additional sync input is connected with output of clock pulse generation. EFFECT: higher speed of response, accuracy and reliability of recorder. 4 cl, 8 dwg
