Graph
The graph updates with each new set of sweep data received by the

error message automatically is displayed if the sweep telemetry level
is too low.
Graph Information

cies are updated to match the zoom view.
Marker Status Area
The Marker Status area displays the marker frequency in MHz, the
meter-generated signal level, and the headend measured signal level
frequencies for which the markers are on. The black square around
the frequency indicates the active marker. The delta label between the
