Performance Tests Power Tests
92 Agilent 81600B Tunable Laser Source Family, Fourth Edition
At the start of the test the TLS is set:
• To any fixed wavelength, preferably to a wavelength where the highest
specified output power can be achieved,
• To the maximum output power specified for this wavelength or, if a built-
in attenuator is used, to 0 dBm.
• Such that any modulation is off.
The output power is measured and compared to the displayed power
value. For simplicity, the start value is defined as a reference, and all
subsequent differences between the measured and displayed power
values are compared to this reference.
Output power is decremented in 1 dB steps.
At the end of the test, the TLS is set to its minimum output power.
Test Procedure - Low SSE output
This test procedure is applicable to the:
It measures the power linearity of the module at the outputs indicated.
1 Set up the equipment as shown in Figure 26:
