AR/GE/FE/U 80/80X Installation Manual 3.10 Auto Calibration The Auto Calibration feature scans the receive signal across the entire (broad) band and flattens the levels, much like the equalizer on your home or car stereo. The radio system is said to be in “Alignment Mode” when it is first powered up with no fiber connected. The Auto Calibration mode is triggered ON as soon as the fiber cable is connected.
AR/GE/FE/U 80/80X Installation Manual If you do not obtain a Quality voltage of 2VDC, do not proceed to calibrate the system. Ensure you are aligned and achieve your target RSL level. This can be confirmed for your path distance by looking up the RSL voltage to distance curve in Appendix B. 4. At this point you need to connect the fiber cable (or a fiber loopback if no network gear is terminated to the far end of the fiber). If using a fiber loopback, remove immediately when the Link LED starts blinking.
