Measuring instrument tested Optical power meter
Optical fiber
Fig. 6-1
Step Operation
1 Set up a measurement system like that shown in the figure, above.
2 Set the optical output mode of the measuring instrument to be
tested to the CW mode, and set ATT at 0 dB.
3 Set the measuring instrument to be tested to the center frequency.
4 Measure the optical output level by the optical power meter.
5 Check that the value measured comes within the specified level.

Fig. 6-2
Step Operation
1 Set up a measurement system like that shown in the figure,
above.
2 Set the optical output mode of the measuring instrument to be
tested to the CW mode, and set ATT at 0 dB.
3 Set the measuring instrument to be tested to the center fre-
quency.
4 Adjust the optical output to or below the maximum input level
of the optical frequency counter using the optical attenuator.
5 Measure the optical frequency by the optical frequency counter.
6 Check that the value measured comes within the specified
value.
