The Optical Spectrum Analyzer has build-in source when ordered as an option. The source type is either ASE source or EELED. After the instrument boots up, the source is turned on by default.
One way to make it off after the boot up is to save/recall instrumentâ€™s setting as instructed below:
1. Go to Systems menu -> Options -> Light Source -> turn OFF 1300nm and 1550nm.
2. Go to Save/Recall menu -> Fast Meas SAVE to save the current system settings.
3. The next time you switch on the OSA, go to Save/Recall menu -> Fast Meas RECALL to recall the system settings, it only takes 2 steps and the recall will be completed in few seconds.
The source such as EELED has no problem to just leave the source turned on according to laser safety information since the power is less than 50uW per wavelength and is thus well within class I (refer to Userâ€™s Guide p1-26 on edition 4).
It is anyway recommended to use a cap or cover on the source output connection when it is not used. This will protect not only from light exposure but also the connector clean.
