D
c. Select display in dBm.
3. Set the TLS
a. Set the power to maximum possible value:
i. Press
4
Output Power
5
.
ii. Use the Modify knob to increase the displayed value to the maximum.
b. Set the wavelength to
HP 8167A 1280nm
HP 8168D 1490nm
HP 8168E 1475nm
HP 8168F 1450nm
c. Activate the laser output.
Note
The laser output is limited to its maximum possible value at this
wavelength, the display will probably show
excessive: P =
x.yy
W
4. Measure the output power with the 8153A and note the result for this
wavelength in the test report.
5. Increase the wavelength on the TLS as shown in the test report.
6. Increase the wavelength on the 8153A by the same amount that you have
increased the wavelength the TLS.
7. Repeat list item 4 to list item 6 until the end of the wavelength range of the
TLS is reached.
Power Linearity
1. Set up the equipment as shown in Figure D-4 (HP 8167A, 8168D,E,F).
