Performance Tests Wavelength Accuracy
78 Agilent 81600B Tunable Laser Source Family, Fourth Edition
Figure 20 Absoute and Relative Wavelength Accuracy.
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.
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.
