Locate the 6 ft connector cable assembly with SMA connectors on both ends. Plug the SMA connector into the LASER CURRENT OUTPUT plug and the Hirose connector into the LASER TEMP OUTPUT on the Laser Controller. Make sure that the nearby Laser switch is in the OFF/RESET position (down). While grounded, remove the SMA terminator connected to the Laser. Connect the other end of the SMA cable and Hirose connectors to the DBR module. | Locate the 6 ft connector cable assembly with SMA connectors on both ends.

- | Adjust the Coarse and Fine Current controls on the Laser Controller to place a transition peak at the center of the oscilloscope screen. Reduce the ramp amplitude so you can clearly see the hyperfine transitions (adjust fine current as necessary). As you lower the ramp amplitude and bring it back, you will see the spectroscopy on the oscilloscope expand and contract about a single point on the oscilloscope. The point should be near the center of the oscilloscope. Adjust the horizontal position on the oscilloscope to put this point in the //**exact middle**// of the oscilloscope screen.
