INTUN Series Tunable Lasers
•
Modulation Input: Modulation input for analog optical power modulation. Maximum signal amplitude is
2 V
P-P.
•
Wavelength Output: Analog output signal representing the actual wavelength. The output amplifier is
0 to 4 V. The load should have an impedance of 10 kΩ or higher.
•
Power On: LED indicates main power on.
•
Laser On: LED indicates laser optical power on.
•
Modulation On: LED indicates Analog Dither enabled. The optical power can be modulated with the
modulation input BNC connector.
•
System Error: LED indicates a fatal failure.
•
USB: This is the communication interface to the host controller (Windows
USB cable.
•
Interlock: To enable laser output, the DB9 connector pin 1 and pin 2 must be connected. This feature
should be used to comply with safety requirements where applicable.
•
DC +48 V: 48 V DC Main Power Input (48 V power supply included).
