随着科学技术的发展,电子技术的作用显得越来越重要,同时,电子工业也得到了迅速的发展,特别是信号发生器、电源、示波器和频率计等台式通用电子仪器,已从建国初期生要依靠外援走向自产自销,现在又发展到了同种仪器多厂家生产和进入国际市场的新阶段。因此,在满足性能指标的前提下,如何使仪器进一步做到价廉物美,就成了使用方,特别是生产厂所共同关心的课
With the development of science and technology, the role of electronic technology is becoming more and more important. At the same time, the electronics industry has also been rapidly developed. In particular, desktop general purpose electronic devices such as signal generators, power supplies, oscilloscopes and frequency meters have been developed since the founding of New China Students rely on foreign aid to self-production and marketing, and now has developed into a new phase of multi-instrument production and enter the international market. Therefore, under the premise of meeting the performance index, how to make the instrument more cost-effective, it becomes the user, especially the common concern of the manufacturing plant
