Module Interaction Test

N O TE
The following functional test assumes the use of modules which are
within specification.
1 Setup the test equipment as shown in Figure 199:
Insert the fixed laser source module in slot 1 and the power sensor
in slot 2 . If you use the Agilent 8164A/B Lightwave Measurement
System, insert the back-loadable Tunable Laser module, if available,
in slot 0.
2 Switch on the mainframe and wait until it has booted.
3 Press Preset, the green hardkey, to set all parameters to their
default values.
4 Ensure that [λ], the wavelength of the power sensor module equals
[λ], the wavelength of the laser source in slot 1.
5 Ensure, the attenuation of the laser source is set to 0.00 dB.
6 Move to the power sensor channel, move to [P], press
[Power Unit], and select <dBm> from the menu that appears.
7 Press the key beside the laser output on the module front panel to
switch on the laser source.
8 Note the power reading of the power sensor in the test record. The
Module Interaction Test ends here if you use the Agilent 8163A/B.
N O TE
If you use the Agilent 8164A/B, perform steps 9 to 12.
If you use the Agilent 8166A/B, perform steps 9 to 15.
9 Switch your mainframe off, by pressing the Power Key.
10 Move the laser source module from slot 1 to slot 3, and the power
sensor module from slot 2 to slot 4.
11 Connect the output of the laser source in slot 3 to the input of the
power sensor in slot 4.
12 Repeat step items 2 to 8.
