| Abstract |
Background. The converter of time intervals in code designed for constructing time interval meters, for example, front durations and decay times of pulse signals in determining the maximum rates of rise and fall of the output voltage of operational amplifiers.
Materials and methods. The converter was tested using a specially designed system with two synchronized DDS-generators AD9851.
Results. Structural diagram of the stand for the research of the time interval converter in the code TDC7200, the procedure for examining the time interval converter in the code are given. The study of the time interval converter in the code TDC7200 showed that after correcting the detected additive component of the measurement error, the relative error in the measurement of the time intervals by the TDC7200 converter in comparison with the frequency counter of CH3-64/1 does not exceed 1.2 % in the range from 0.2 μs to 10.0 us.
Conclusions. The possibility of using a time interval converter in the code TDC7200 for constructing meters of small time intervals and a meter for the rate of rise (fall) of the output voltage of the op-amp
