Calibrator Multi-Pt Align
Calibrator Multi-Pt Align
Adjusts the mechanical position of the instrument's internal optical compo-
nents ensuring amplitude accuracy of your measurements. Before initiating
the alignment, connect the internal calibrator to the front-panel input connec-
tor. Refer to "External Multipoint Wavelength Calibration" on page 2-17
The instrument automatically sets the start wavelength at 1490 nm, stop
wavelength at 1590 nm, span, and reference level, and then performs a fully
automatic, internal auto align. The input signal is aligned at equally spaced
alignments (minimum 50 nm spacing between points) for the internal, multi-
mode fiber or (minimum 5 nm spacing between points) for the external, sin-
gle-mode fiber (Agilent 86144B/86146B only).
Error 5056, Trajectory align cannot find input signal, will occur if a broadband
light source is not connected to the front-panel input connector.
Error 5060, Trajectory align failed, will occur if the align procedure failed.

Center Wavelength (WL)
Sets the center wavelength using the knob, step keys, or numeric keys. The
span remains constant. The center wavelength and the start and stop wave-
length settings are related as follows:
