e.
Press
NNNNN
# to skip over the dwell parameter .
f. Type in 1 on the keypad and press 4 ENTER 5 to set the number of times
that the sweep is to be performed.
13.
On the laser source , press
NNNNNNNNNNNNNNNNNNNNNN
Pmax ! P to set the output power to the highest
value that can be maintained for the full sweep range .
14. On the power meter:
a. Set to 1535nm
(4 Pa ram 5 ! !1535.0nm).
b. Make sure that the parameter cursor is in the units position (that is , at
the second \5").

15. Make sure that the laser source is still active .
16. On the laser source , press
NNNNNNNNNNNNNNNNNNNN
Manual .
17. Read the value for the power at 1535nm on the multimeter .
18. Repeat the following steps at each wavelength in the sweep range
a.
On the laser source , press
NNNNNNNNNNNNNN
Next .
b. On the multimeter , increment (press 4 * 5 ).
c. Read the value for the power at the wavelength on the multimeter .
19.
On the laser source , press
NNNNNNNNNNNNNN
Stop to end the sweep .
This procedure can be used in practice to measure the wavelength characteristic
of a component.
