45、 a tuneable narrowband light source, the term linewidth is commonly preferred. Often defined by the width at a set power distance from the peak power level of the device (i.e. 3 dB BW or 1 dB BW). The bandwidth shall be defined as the distance between the closest crossings on either side of the cent
