D Single-Mode/Multimode Module Performance Tests Test V. E6006A Power Meter Submodule
262 E6000C Mini-OTDR User’s Guide, E0302
Connect equipment 1 Connect the equipment as shown in Figure 87.
NOTE If you are performing the optional accuracy test at
850 nm, it is sufficient to measure at the highest power
level. This means that you do not need to use an
attenuator: you can connect the laser source directly to
the optical head using an Agilent 81501AC patchcord.
2 Disable the laser source and attenuator; zero the power
meter (press {Z
ERO}).
Reference Measurement
Settings 3 Set the laser source to 1310 nm (nominal).
4 Set the Laser Source to ATT=0.
5 Set the power meter and the attenuator to 1310.00 nm.
6 Set the power meter to M
EASURE mode; select
parameter T=100ms; switch AUTO range on.
Set up equipment 7 Enable the Laser Source and the Agilent 8156A output,
and wait 3 minutes until the laser has settled.
8 Set the attenuation of the attenuator to 0.00 dB.
9 On the power meter, press [dBm W] to get the display
reading in W.
Note result in test record 10 Note the displayed reference measurement value on the
power meter in the test record.
Repeat for other attenuations 11 Repeat steps 9 and 10 for all attenuation values listed
in the test record.
Measurement of DUT
Connect attenuator to DUT 12 Connect the attenuator output cable to the DUT, as
shown in Figure 88.
