Viewing the Input Power Level
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.
