说明： 本系统基于直接数字频率合成技术；以凌阳SPCE061A单片机为控制核心；采用宽带运放AD811和AGC技术使得50Ω负载上峰值达到6V±1V；由模拟乘法器AD835产生调幅信号；由数控电位器程控调制度；通过单片机改变频率字实现调频信号，最大频偏可控；通过模拟开关产生ASK、PSK信号。系统的频率范围在100Hz～12MHz,稳定度优于10-5，最小步进为10Hz
(The system is based on Direct Digital Synthesis technology to Sunplus SPCE061A Singlechip for the control of the core the use of broadband and AGC OPAMP AD811 technologies enable 50Ω load peaks reach 6V ± 1V generated by the analog multiplier AD835 AM signal from NC program-controlled potentiometer modulation change the frequency of the word through the realization of single-chip FM signal, the largest controllable offset through analog switches have ASK, PSK signal. Frequency range of 100Hz ~ 12MHz, stability better than 10-5, the smallest step to 10Hz)
