Marker Control State - DEVA Broadcast DB7000 Maintenance And Operating Instructions

Marker control state:

Two markers, named "A" and "B" are available in Bandscan page. SB1, SB2, Left and Right
buttons control the visibility and position of the Markers.
Buttons (SB1) / (SB2) control Marker A / Marker B appearance. According to your needs the
markers can be:
•
hidden – marker is not visible;
•
shown – marker is visible but not selected;
•
selected – marker is visible and selected.
When markers "A" and/or "B" are visible (shown or selected) a readout about X and Y axes
will appear on the left side of the data plot. If both markers are visible, the differential "Marker B
minus Marker A" value will be displayed at the bottom left of the screen.
The selected marker is represented as highlighted, dashed line; marker's readout is also
highlighted. Only one marker at a time can be selected. If only one of the markers is visible, it will
be always selected.
Following is a diagram explaining the transition between these states:
SB1 or SB2
Left / Right Buttons – move the selected marker to the left or right with one screen pixel
increment.
The step resolution of marker movement depends from the selected X span.
NOTE:
