| 摘 要： | YIG调谐滤波器(YTF)作为预选器广泛应用于现代频谱分析仪中,对高频段的带外和镜像响应进行有效的抑制.传统的预选器调整都通过梳状信号发生器完成.提出了一种新的自动调整算法,能有效的对由温度引起的预选器调谐频率变化进行补偿.详细介绍了该算法的推导,并通过一组实测数据验证了该方法的有效性.最后对本方法的局限性进行了说明.

| Abstract: | YIG turning filter (YTF) used as pre-selector are widely applied in modern spectrum analyzers to reject spurious responses. Traditional way of adjust pre-selector is accomplished with comb signal generator.A novel method is introduced to compensate the error caused by temperature drift. The deducing of method is discussed in details. A group of actual data proved the validity of this method. At last,the limitation of this method is illuminated. |
