You can make acquisitions according to three different modes:
³
Quick Check
³
Standard
³
Advanced
Each mode is explained in Setting up General Acquisition Parameters on
page 21.
The FTB-5600 does a series of actions in taking a measurement.
³
The instrument takes an OTDR trace and displays it. This step only
takes a few seconds. At this point, you should inspect the trace to see if
there are any problems.
³
Then, the instrument measures the SOPs. This will take more or less
time depending on the accuracy and sensitivity requested. The
remaining time and SOPs to measure are indicated in the status bar of
the application. After measuring about 10 SOPs, you will see a
temporary cumulative PMD curve.
³
Once all of the SOPs are acquired, the instrument computes the actual
PMD curve.

In order to use the FTB-5600 to its most optimised level, you must
have a solid knowledge on how OTDRs function.
