Power Linearity - Test Using Attenuation
Follow the steps below to measure the power linearity (while using
attenuation) of any one of the following:
• Output 2, the High Power output, of the Agilent 81480A
• Output 2, the High Power output, of the Agilent 81680A
• Output 2, the High Power output, of the Agilent 81640A
• Agilent 81682A #003
• Agilent 81642A #003
1 Set up the equipment as shown in Figure 21.
2 Move to the Tunable Laser channel of the Agilent 8164A Lightwave
Measurement System and press [Menu].
3 Set the menu parameters to the values shown in Table Table 5.
For Agilent 81480A, Agilent 81680A, Agilent 81640A,
Agilent 81642A#003 Agilent 81682A#003:
Set <Power Mode> to <Manual Att>.
4 Set the wavelength and power for each Tunable Laser module to the
values given in Table Table 13.
NOTE If you use the Agilent 81480A Output 2, Agilent 81680A Output 2, or
Agilent 81640A Output 2 with attenuation, use the table “Power
Linearity Output 2, High Power by attenuator” on page 121 or “Power
Linearity Output 2, High Power by Attenuator” on page 135
respectively.
If you use the Agilent 81682A #003 with attenuation, use the table
“Power Linearity 81682A #003 by Attenuator” on page 149.
If you use the Agilent 81642A #003 with attenuation, use the table
“Power Linearity 81642A #003 by Attenuator” on page 161.
5 Perform the steps 5 to 16 of the “Power Linearity - Low Power Test”
on page 71.
