Managing WDM Test Results

³ Wavelength offset (nm): indicates the offset value applied on the

wavelength. 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.

Entering a value in THz is not possible. The wavelength offset

appears below the graph, on the right, next to the arrow.

³ Power offset (dB): indicates the offset value applied on the 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.

³ Bandwidth at (dB): indicates bandwidth measured by taking the

width of a signal at x dB from the peak.

5. Press OK to save the changes, re-analyze the trace and close the

window, or press Cancel to exit without saving.

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

values.
