Performing Reference Measurements
Note: When choosing a type of reference, take into account that a reference
measurement must have been previously taken for the type of the tests you
will perform. For instance, if an IL/PDL reference measurement has been
previously taken, you will be able to perform IL tests. However, with such a
reference measurement, ORL tests will not be possible.
To perform reference measurements:
1. If the System menu is grayed out, that means no test has been created
since the application was started. Consequently, no references can be
performed until you start a new test. For more information, see Starting
a New Test on page 118.
2. Select References from the System menu of the main window.
3. Select the reference type you need.
4. Connect start fiber to the specified switch port and power meter
channel.
5. When you are satisfied with the value displayed in the power meter
monitoring box, click Start.
6. Repeat steps 4 and 5 for each switch port. The connection information
section provides you with the number of the switch port and the
number of the power meter channel to which the patchcord must be
connected.
Note: You only need to reference the switch ports that you plan to use, starting
sequentially at channel 1.
7. Repeat the above procedure for each reference type you need.
8. When you are done with reference measurements, simply click Close
to return to the main window.
Note: The zone labeled Instructions guides you through the whole reference
measurement process.
