Wavelength Accuracy Performance Tests
Agilent 81600B Tunable Laser Source Family, Fourth Edition 85
Figure 22 Wavelength Repeatability.
At the start of the test the TLS is set:
• To its lowest specified wavelength,
• To the highest power the TLS can deliver over the full wavelength range,
• Such that any modulation is off,
At the end of the test, the TLS is set to its maximum specified wavelength.
Test Procedure
This test procedure is applicable to the:
It measures the wavelength repeatability of the module at the outputs
indicated.
Attenuate the Power Output from the TLS Reduce the output power
delivered by the TLS to a level compatible with the capabilities of the
wavelength meter.
Use the TLS module’s built-in attenuator, or an external attenuator.
