Connectors
TRIGGER IN:
Connect a 5 V TTL signal. It is used in the “SEQUENCE (with external trigger)” and “ANALOG (with
external trigger)” modes. In these modes, the TRIGGER IN is used to trigger the controller to switch
wavelength.
ANALOG IN:
Connect a 0 - 5 V analog signal. It is used in the ANALOG mode. In this mode, the filter adjusts its
wavelength, in accordance to the voltage of the analog signal. The ANALOG IN signal tunes the filter’s
passband wavelength from the shortest wavelength (0 V,
𝑊𝑠
) to the longest wavelength (5 V,
𝑊𝑙
),
meaning that the voltage step size for analog tuning is V/nm.
