Agilent Technologies N9340A manual Marker, Normal

Key Reference 5

Marker

Accesses the marker control softkeys to select the type and number of markers. Markers are diamond- shaped characters that identify points of traces. Up to six pairs of markers may appear on the display simultaneously; only one pair can be

controlled at a time. The marker that is controlled is called the “active” marker. Pressing [MARKER]

activates the Normal menu key.

Marker

Selects one of the six possible markers. A marker that has already been selected will become active when it is turned on. If a marker has been turned on and assigned to a specific trace, it will become active on that trace if that marker is selected.

Key access: [MARKER]

Normal

Activates a single frequency marker at the center of the active trace if a marker is not already displayed. If a marker is displayed before the Normal function is enabled, the marker is enabled at the position of the selected marker. The marker number is indicated above the marker. The knob and/or arrow keys move the marker left or right. If a value is entered from the numeric keypad, the marker is moved to the trace point nearest to that value. Annotation in the active function block and in the upper right corner indicates the frequency

and amplitude of the marker (time and amplitude, if in zero span.) Pressing Normal turns off the Delta

function and moves the active marker to the delta marker position.
