一种程控标准信号源的设计

The Standard Signal Power Source of Program Controlling

介绍了用间接频率合成器(IS)、数字波形发生器以及程控衰减器等构成的标准信号源,该 信号源只要加上功率放大器,即可实现电力检测仪表最先进的校验技术中的程控标准功率源.整个系统 以单片机为控制核心,实现了频率、相位、幅值的数显及步进调整.

The standard signal power source of program controlling made up of indirect frequency synthesize, data-waveform generator and prgramm attenuation is introduced in the paper. The signal soure with amplifier can accomplish the program controlling standard signal power source among the most advanced check technique in electic testing instument. It is based on a microprocessor, realizing the digital display of frequency, phase and amplitude and adjusting them step by step.
