3 Overview

Calibrator ECG, EEG and heart Calibrator, Calibrator EEG (without the need to distinguish between three test When the instrument's personality, hereafter referred to as "Calibrator") is used for ECG, EEG machine to implement the technical indicators Verification of special equipment. According Calibrator dedicated master generates test signals principle can be divided into two types. Feng standard digital signal generated by the analog type Calibrator for verification by the use of a variety of standard signal. digital type Peak can be input to the analog-digital control consistent. Fengfeng standard analog signal by the analog circuit to generate Calibrator for test use, a variety of standard signal. Analog Consistency is adjusted by the value of the hardware implementation.
