By changing the working mode of the frequency spectrum monitor (FSM), the radar can run in the frequency segment with lower noise disturbances, and the ambient noise data obtained by FSM ca.

该方案通过灵活设计频谱监测部件的工作方式，不但能使雷达工作在干扰较低的频段，而且还可充分利用频谱监测所得的外界噪声数据。

We can monitor many parameters and characteristics by measuring TEN, such as surge frequency, spectrum width, threshold current, mode jump and stability of output light power.

通过对激光的电噪声的测量可以监测激光器的诸多参数和特性，如弛豫频率，谱线宽度，阈值电流，模式跳变及输出光功率是否稳定等。
