6. Calibrating the Product
6.1 Performing Power Calibration
Subject The power calibration procedure calibrates the laser output power. The procedure
requires the use of an optical power meter.
Procedure 1. Connect the laser output of the product to a power meter, (see section Connecting
External Optical Devices to the product, p. 22 ).
2. Enable the laser output (see section Enabling/Disabling the Laser Output, p. 26 ) .
3. Press the 2nd + P function keys to activate the power calibration procedure.
The tunable laser moves to a short wavelength within the tuning range and displays
the power level corresponding to the current calibration data.
4. Measure the power level at the first wavelength on the power meter.
5. Enter the reading at the prompt
P =
.
The tunable laser moves to a long wavelength within the tuning range and displays
the power level corresponding to the current calibration data.
6. Measure the power level at the second wavelength.
7. Enter the reading at the prompt
P =
.
The power calibration is now complete and the instructions reference the new power
calibration data.
Caution
This procedure corrects the factory-set calibration data.
• Do not perform this procedure unless you actually intend to correct this
data.
• Do not perform these procedures unless you have calibrated sources.
