Marker Shortcuts

In addition to the Markers menu, the following can be used to set up and move markers:

• mouse shortcuts
• keyboard shortcuts
• marker tools

Mouse shortcuts

• Click on the marker tool icon of interest from the Markers Toolbar (Select Area tool , Marker tool , Band Power tool , Time Gate tool ), then click and drag in the trace to place the marker.

• Right-click in the trace for a context menu with marker selections.

• Drag the marker or just click the location for the currently selected marker to move.

• Marker to peak: right-click in trace, click Peak.

• When the Band Power tool is active and you hover the over one of the Band Power marker's edges, the cursor will change to a left-right arrow and you can drag the edge to change the band power span.

• In the Markers Window, click anywhere on a marker readout line to select the corresponding marker as the active marker (the trace containing the marker will also be made the active trace). Double click the marker readout X position (or Z position) and type the marker position. The keyboard arrow keys or the mouse wheel can also be used to change the highlighted marker readout value, and move the marker.

• When there are multiple markers on a trace, click on the marker shape (diamond or 'X') to select the marker as the active marker.

• For information on moving spectrogram markers with the mouse, see moving spectrogram markers.

Keyboard shortcuts

The following shortcuts all refer to marker search functions.

• Home moves the marker to the first point

• End moves the marker to the last point

• Page Up moves the marker to peak

• Page Down moves the marker to minimum

• ¬ moves the marker one point to the left

• ® moves the marker one point to the right

• ↑ moves the marker to the next larger peak

• ¯ moves the marker to the next smaller peak

• Ctrl+ ¬ moves the marker to next peak to the left

• Ctrl+ ® moves the marker to next peak to the right

Markers on OFDM traces

The information below describes only the differences in marker shortcut operation for OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. trace data that contains Z-axis information (OFDM Error Vector Spectrum and OFDM Error Vector Time, for example).

• ¬ moves the marker to the next smaller value along the x- or z-axis as specified by the active (highlighted) marker readout. To change axis, select the non-active x- or z-axis marker readout field.

• ® moves the marker to the next larger value along the x- or z-axis as specified by the active (highlighted) marker readout. To change axis, select the non-active x- or z-axis marker readout field.

• ↑ moves the marker to the next higher y-value along the z-axis for the current x-axis position. This key will not move the marker in the x-axis dimension.

• ¯ moves the marker to the next lower y-value along the z-axis for the current x-axis position. This operation will not move the marker in the x-axis dimension.

• Ctrl+ ¬ moves the marker left one x axis point to the z axis point that has the nearest y value to the current marker y value.

• Ctrl + ® moves the marker right one x axis point to the z axis point that has the nearest y value to the current marker y value.
