Alignment lnstructions
General Notes
The following data are stored in EEPROM U13:
-
Linearity corrections for 131 0 nm
-
Absolute level corrections for 850 nm, 1310 nm and 1550 nm
-
Temperature alignment data
So that these alignments can be carried out when the instrument is serviced, instruments from
series C have a special integral alignment routine which makes it possible to record and store
the alignment values. This software can be retrofitted to series A and B instruments (EPROM
U14).

Accuracy
Wavelength dependence
The technical data of the OLP-10115 are strongly wavelength-dependent. Therefore, sources
with selected wavelenths are required to
carry
out alignments. If the wavelengths of the sources
differ from the nominal wavelengths, the measurement error of the OLP-lo/-15 may increase.

Preparations
-
Ambient Conditions: Moderate lab conditions, 23 'C
f
3 'C.
-
Before carrying out the function test, the optical connectors must be carefully cleaned and
inspected.
