Instruction Manual

MAX-700 51
5 Testing Fibers in Auto Mode
Auto mode automatically evaluates fiber length, sets acquisition
parameters, acquires traces, and displays event tables and acquired traces.
In Auto mode, you can set the following parameters directly:
 Test wavelengths (all selected by default)
 Fiber type (singlemode, singlemode live, or multimode) for models
supporting these fiber types
 Autorange acquisition time
 IOR (group index), RBS coefficient and helix factor
For all other parameters, the application uses those defined in Advanced
mode, except that analysis is always performed after acquisitions.
If you ever need to modify other parameters, go to Advanced mode (see
Testing Fibers in Advanced Mode on page 55 and Preparing Your MAX-700
for a Test on page 41).
In Auto mode, the application will automatically evaluate the best settings
according to the fiber link currently connected to the unit (in less than
5 seconds). If you interrupt it, no data will be displayed.
Fiber characteristics are evaluated only once per session. Other fibers you
connect to, within the same cable, will be tested with the same settings.
When you start testing another link, you can reset these parameters.
Once this evaluation is complete, the application starts acquiring the trace.
The trace display is continually updated.
Note: You can interrupt the acquisition at any time. The application will display
the information acquired to that point.
