| Abstract: | IC is a powerful function parts of appling universally. It is more and more extensive application in the automatic control system and testing instrument and electron equitmcnt. Therefore. IC parpcment were quikly and accurately tested. This paper estimated paracmeters of IC amplifiers of stcp-by-stcp excitation.step-by-step sample.least squares. Based on the designing of hardware, software of system was debugged. These main programer frames arc instruduccd in detail.The function of zera adjustment and deviation compensation can be realized in the system. Under the system programmers controlling.the system can autmat-ic measured. The principle of measuring system was completely newly in our country. |
