I have my large slot (81640A/680A/642A/682A) tunable laser connected to an OSA. Why don‘t I see any change in the measured spectrum of the laser when coherence control is activated?

- Coherence control increases the linewidth of the laser from 100KHz to 500MHz(typical). At 1550nm this relates to a wavelength change of .004nm. The wavelength resolution of the OSA is .06nm resolution bandwidth minimum. It cannot resolve a .004nm change.
