Sampling resistance is both the signal to noise ratio to be good and avoiding to produce the oversized survey signal.
选择采样电阻，既要信噪比好，又要避免产生过大的测量信号。
The precision LD current driver can be used in many kinds of small-medium power LD by adjusting the maximum limited current or the sampling resistance.
通过适当调节最大限制电流或采样电阻，该电流源可应用于各种型号的中小功率半导体激光器。
