2008新款200MHz段可调256频多频接收机通过频率设定端子,可自设定多达256个的频率信道.本接收机起始频率值为223.000MHz(频率设定端子全插上,二进制电平00000000),步进为25KHz(0.025MHz),最高工作频率值为229.375MHz(频率设定端子全空,二进制电平11111111)
其他工作频率信道设定方法如下
如图,频率设定编码开关共八位,最下处为第一位;端子插上电平为0,不插上为电平1.
本接收机的八个端子频率设置方法和数学上的二进制/十进制换算方法原理相同,
注意:由于本接收机的频率步进最小值是25KHz(0.025MHz),所以能工作的频率值必须是25KHz(0.025MHz)的整倍数,且范围在最低工作频率223.000MHz和最高工作频率229.375MHz之间
(一) 使用二进制中的”二除取余法”,按需要的接收机工作频率设定八个端子电平位
以准备为本接收机设定226.875MHz工作频率为例子,首先将此值减去223.000MHz得3.875,然后除以0.025(步进值)得155.
使用”二除取余法”,得10011011(注意最前位为高位),此即为频率设定端子第一到第八位的电设定值(如图)
(二)从已设定的八个电平位换算出接收机工作频率,使用”二除取余法”,得
223.0000+(第八位电平X27+第7位电平X26+第6位电平X25+第5位电平X24+第4位电平X23+第3位电平X22+第2位电平X2+第1位电平)X0.025
以板上频率设定端子电平10101011(注意最前位为高位)为例子,代入公式,得223.0000+(1X27+0X26+0X25+1X24+1X23+0X22+1X2+1)X0.025=227.275MHz
(2的0次方,1次方,2次方~~~7次方分别等于1,2,4,8,16,32,64,128)
(三)使用列表快速查对及设定接收机工作频率值(如下表)
