目前,中等学校配备的一般为J2463型高频信号发生器.这种发生器输出信号频率范围宽,从0.4MH_2到130MH_2,可以输出等幅波,也可以输出已调波,基本上满足了教学实验的需要.如果给J2463型高频信号发生器增加一只φ3.5mm二芯插座,就可使该机增加另一种功能.即可用音频信号如电唱机拾音信号、录音机输出信号等对高频信号进行调制,成为发射机.在接收端或被检测机如收 At present, secondary schools are generally equipped with J2463 high-frequency signal generator.The output frequency range of this generator is wide, ranging from 0.4MH_2 to 130MH_2, it can output constant amplitude wave and output modulated wave, which basically satisfies the teaching Experimental needs .If the J2463-type high-frequency signal generator to add a φ3.5mm two-core socket, you can make the aircraft to add another function that is available audio signals such as record player pickup signal, the recorder output signal, such as high Frequency signal modulation, a transmitter. At the receiving end or the detection of machines such as income
