There is an urgent need to improve system design of calibration equipment which allows us to determine parameters and characteristics of medical electrodes. Technical characteristics of a hardware and software system for researching medical electrodes are depending on amplitude-frequency responses of a measurement analog channel. This channel consists of an instrumentation amplifier, a cascaded chain of operational amplifiers including programmable-gain amplifiers and a low-pass filter, therefore calculating amplitude-frequency responses of a measurement channel is a multiparameter problem. This problem can be solved efficiently by simulation with help of Matlab. Simulink-model of a hardware and software system for researching medical electrodes is suggested. The model provides the correct design of a measurement channel. It is subject to design criteria such as accuracy of frequency band and a reduction in gain.
