AQ6370B - PASSIVE COMPONENT TEST
Wide dynamic range measurement using a synchronous wavelength sweep function* of a tunable laser source and optical spectrum analyzer is suitable for evaluating passive devices and components with a high crosstalk ratio. The tunable laser source emits a single wavelength, and the AQ6370B's filter characteristics cuts source spontaneous emission and scattered light. Thus, this system can achieve wide dynamic range over 70 dB.
* TLS SYNC function. It supports AQ4320, AQ4321 and AQ2200-136 Tunable Laser Source.
In conjunction with a white light source, an ASE light source or other broadband light source, you can simply perform evaluation of passive devices such as WDM filters and FBG. The AQ6370B's superb optical characteristics enable higher-resolution and wider dynamic range measurements.
The built-in optical filter analysis function simultaneously reports peak/bottom wavelength, level, crosstalk, and ripple width.
