Sixth Edition
7 Set the HP 8153A to the following settings:
a Zero the HP 81532A; press Zero.
b Select automatic ranging; press Auto as required.
c Set T, the averaging time, to 500 ms.
d Select dB as the power units.
e Set the l, the wavelength, to the same as your Tunable Laser
module, as given in Table Table 11.
8 Press the key beside the laser output to switch on the laser output.
For the Agilent 81480A, Agilent 81680A and the Agilent 81640A,
press the key beside Output 1, the Low SSE output.
9 Record the power displayed by the HP 8153A.
10 Press Disp−>Ref on the HP 8153A.
11 Change the power setting of your Tunable Laser module to the next
value listed in the test record and record the power displayed by the
HP 8153A again.
12 Record the power displayed by the HP 8153A as the "Measured
Relative Power from start".
13 Calculate the "Power Linearity at current setting as the sum of
"Measured Relative Power from start" and "Power Reduction from
start".
14 Repeat item 11 to item 13 for all power levels listed in the test
record.
15 Note the maximum and minimum values of the calculated Power
Linearity values for the various settings and record these in the test
record.
16 Subtract the minimum values from the maximum values of the
Power Linearity for the various settings. Record these as the Total
Power Linearity for the various settings.
