Auto Align & Add to Trajectory
Auto Align & Add to Trajectory
Allows alignment at several wavelengths, ensuring amplitude accuracy of your measurements.
Before initiating the alignment, connect a broadband light source to the front-panel input con-
nector. (You may add and/or update the existing points in the trajectory table.) Press Auto Align
Preset to clear the table.
Turn on an active marker and manually place the marker at the desired wavelength. If an active
marker is not turned on, the instrument will automatically turn on an active marker and auto align
at the largest input signal. The minimum recommended spacing between points is 5 nm for the
external, single mode fiber (Agilent 86146B only) and 50 µm for the internal, multi-mode fiber.
The span must be >3 nm for the single mode fiber and >25 nm for the multi-mode fiber.
N o t e Error 5001, Auto align cannot find input signal, will occur if a broadband light source is not
connected to the front-panel input connector.
Error 5070, Trajectory Add Failed, will occur if the trajectory table is full or the computed trajectory
table is invalid.

Auto Meas
Pressing the Auto Meas button on the front panel of the instrument performs an automatic mea-
surement of the largest signal found in a full span sweep and places a marker at the signal peak.
The signal must have at least 10 dB of excursion.

external, broadband or narrowband light source. If there is insufficient signal power, the auto-
matic measurement will not be performed, and a warning message will be reported. This auto-
matic measurement routine is normally the best way to adjust sensitivity while maintaining the
fastest sweep rates.
