Performance Tests
Test 1. Absolute Wavelength Accuracy
Test 1. Absolute Wavelength Accuracy
Description
Wavelength accuracy is verified using traceable light sources such as the fol-
lowing devices:
•Stable lasers
• Gas lamps
• HeNe gas lasers
CAUTION
Do not exceed +18 dBm source power. The Agilent 86120B’s input circuitry can
be damaged when total input power exceeds 18 dBm.
Procedure
Use three or four light standards that cover the Agilent 86120B’s wavelength
range. Connect the traceable sources to the Agilent 86120B and verify that the
Agilent 86120B is reading the sources to within the absolute wavelength accu-
racy specification.
