Power Linearity
Power Linearity - Low Power Test
To measure the power linearity of the Low SSE output, Output 1, of
the Agilent 81480A, Agilent 81680A, or the of the Agilent 81640A:
1 Set up the equipment as shown in Figure 21.

Test Setup for Low Power Linearity Tests
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.
<Power Mode> does not apply.
4 Set the wavelength and power for each Tunable Laser module to the
values given in Table Table 11.
5 If you are using the Agilent 81680A, Agilent 81480A, or the
Agilent 81640A Tunable Laser module:
Connect the output fiber to Output 1, the Low SSE output.
Set <Optical Output> to <Low SSE (1)>.
6 Make sure the optical output is switched off.
