User Source Multi-Pt Align
Adjusts the mechanical position of the instrument's internal optical components ensuring ampli-
tude accuracy of your measurements. This function is semi-automatic and aligns equally spaced
points within the span and builds the current fiber trajectory table.
page 3-41
Connect an external broadband source to the input connector of the instrument. Then set the
instrument to the desired values:
• start and stop wavelengths (input range 600 nm to 1700 nm)
• span
• >3 nm for the external path (Agilent 86146B only)
• >25 nm for the internal path
• reference level (must be greater than –78 dBm in a 10 nm resolution bandwidth at all points to
be aligned)
The instrument auto aligns at equally spaced points within the span and builds the fiber trajectory
table (maximum of 32 points). To add or adjust a single point in the trajectory table, move the
active marker to the specific wavelength location and press Auto Align & Add to Trajectory. The
Multi-Pt Auto Align progress window opens indicating the percentage of completion and the
approximate time required for the alignment process. To cancel the align, press the instrument
preset key. This table is interpolated to create a linear set of corrections.
If Auto Align is executed after User Source Multi-Pt Align, all of the alignment tracking data will
be shifted. In this sense, auto align is done on top of this alignment.
N o t e 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 5057, Invalid settings for trajectory align, will occur if the start and/or stop wavelength
settings are invalid.
Error 5060, Trajectory align failed, will occur if the align procedure failed.
