³ Output power offset (dB): indicates the offset value applied on

the output power. You can use an offset to adjust your unit. This

does not replace a calibration performed at EXFO, but it can help

you achieve the specifications if you have determined that, for

example, your modules are used beyond the normal allowed. The

power offset appears in the graph, on the left, above the arrow.

To edit the power offset value in percentage, press Edit % button.

The percentage value entered in Edit percentage will be

converted to a corresponding equivalent value in dB.

5. Press OK to save the changes and close the window, or press Cancel to

exit without saving.

Press Restore Defaults to remove all the changes and apply the default

values.
