灵敏度是寻呼机的一项重要指标。由于使用时间长，元件老化等原因，造成寻呼机灵敏度下降等比较棘手的故障。对于灵敏度低的寻呼机，应对其进行寻呼灵敏度测试。测试仪表连接图如下图所示。降低寻呼机的射频输入信号，看其射频信号电平与技术指标相差多少。采用10dB上升法测试
Sensitivity is an important indicator of pager. As the use of a long time, aging components and other reasons, resulting in decreased pager sensitivity and other more troublesome fault. For low pager sensitivity, should be page sensitivity test. Test instrument connection diagram as shown below. Reduce the pager’s RF input signal to see how much its RF signal level differs from the technical specifications. Using 10dB rise test
