5. A long wavelength is automatically displayed 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 long wavelength is set. Check the calibration by setting the tunable laser source to
arbitrary wavelengths and checking the wavelength using the meter. Ensure the differences
between values are less than 0.2 nm.
6. Disconnect the wavelength meter from the tunable laser source. Reconnect the laser input
to the Laser In connector on the source optics module.
Connect the Acetylene Gas Cell to your Receiver.
The acetylene cell is built into the SOM, and can be accessed through the front panel.
Alternatively, you may also use an external gas cell, which could make it easier for you to do
calibrations, if the SWS receiver is not located close to the transmitter. Connect the cell as you
would a DUT
Figure 83. Set up the system in this way to calibrate receiver.
