100 – Operating and Maintenance Instructions
•
Calibrate the SWS to the acetylene trace.
•
Save the calibration values to the EEPROM in the Control Module in the receiver.
•
As an added option, choose whether to restore previously saved calibration values into the
EEPROM from the INI file.
Ensure the tunable laser source is properly calibrated.
For standard laser operation during recalibration, refer to the laser manual for operating
instructions.
1. Ensure that the tunable laser source is properly calibrated. A calibrated wavelength meter is
required for this operation. Start by connecting the output of the laser to the wavelength
meter (Figure 82).
Figure 82. Tunable Laser Source Calibration Setup
2. Set the wavelength of the tunable laser source to 1520 nm for a C-band system or 1540 nm
for an L-band system. Compare the setting with the meter reading.
3. Set the wavelength of the tunable laser source to 1570 nm for a C-band system or 1630 nm
for an L-band system. Compare the setting with the meter reading.
4. If the difference for either reading is more that 0.2 nm, recalibrate the tunable laser source.
Start by pressing the 2
nd
key, followed by the
λ
key. The display automatically shows a short
wavelength in the tuning range. There is a prompt to enter the measured wavelength;
therefore, reading from the meter, enter the measured wavelength on the tunable laser
source using the numbered keys and then press the Enter key. The short wavelength is set.
