Viewing the Input Power Level

The power level indicator is a visual aid to estimate the incoming signal

intensity as detected at the input port. The indicator remains visible at all

times at the bottom of the screen, except during acquisitions.

To ensure more accurate readings of the power level, EXFO recommends

that you perform a nulling first (see Performing a Null Measurement on

page 41). The input power level should be in the green area.
