4 Set the inital wavelength and power of the TLS to:
5 Make sure the optical output is switched off.
6 Zero the power meter. Press [Menu] then select <Zero>.
7 Switch on the TLS output, then wait for 1 minute.
8 Select the logging application.
Press [Appl] then select <Logging>.
9 Within the logging application, set the power meter:
• Select module 2.1
(if 81619A is in slot 2, the 81626B connected to “Head 1”)
•Set
λ, the wavelength, to the same as the TLS module, as given in
step 4,
•Set Range to 0dBm,
•Set Ref mode to Value,
•Set Samples to 4000,
•Set the Averaging Time to 200 ms,
•Set Range mode to common,
•Set Power unit to dB,
•Set Ref to the value given at step 4.
10 Select [Measure] to start the logging application. A progress indicator
is displayed.
11 When the measurement has finished, select [Analysis]
12 From the Statistics window, note the following results in the Test
Record:
• The “max” value as the Maximum Deviation,
• The “min” value as the Minimum Deviation,
•The “
∆P” value as the Power Stability.
