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 connector. (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 wave-
length. 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 mini-
mum recommended spacing between points is 5 nm for the external, single
mode fiber (Agilent 86144B/86146B only) and 50 nm 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.
Note 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 measurement 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. (Refer to “Peak Excursion (Marker Setup Panel)” on page 3-57 for
additional information.) Auto measure requires the connection of an external,
