Accuracy Test
1.
Connect the equipment as shown in Figure 5:
LTS / Power Meter
Attenuator
Source
Figure 5. Test set-up for the Power Meter section Accuracy Test
2.
Switch on all instruments.
3.
Set all instruments to 1310 nm.
4.
Change the attenuation of the attenuator until the reference
power meter displays -10.00 dBm. Note the attenuator setting
in setting 1 of Table 4.
If the light source is not powerful enough to give -4.00 dBm,
set the attenuator to 2.5 dB and correct the appropriate
values in the test report.
Repeat the above for reference power meter readings of
-20dBm, -30 dBm, -40 dBm and -50 dBm (last reading not
relevant to H series power meters).
5.
Measure the DUT:
Re-connect the attenuator output cable to the DUT power
meter port, and select the 1310nm on DUT.
Set the attenuator to its value for setting 1. Note the displayed
power level of the DUT in the test record.
Repeat the above for attenuator settings 2~5.
6.
Repeat the Power Meter Accuracy Test at 1550 nm.
