Test wavelength of OTDR.
Auto Mode: FHO5000 will set best parameters for current test Manual Mode: set parameters manually.
Under averaging test mode(TEST), longer test time has better SNR (Signal Noise Ratio) but takes more
time .
Test distance of OTDR .adjust only in manual mode, in auto mode this item set as "Auto".
Wider pulse has stronger backward signal, OTDR has longer detecting distance but wide pulse width will
cause the saturation of backward signal, make blind area bigger. so the selection of pulse width has
close relationship with the length of fiber. Long fiber has wide pulse width.. pulse width could only
modified in "Manual"mode.
Sampling resolution of test. High resolution has more sample point and high precision, but take more
memory space.
Unit of test result, including km/kfeet/miles.
