3-7 Measurement Setup Cable and Antenna Measurements
Markers
Markers can be applied to active or recalled measurements. The instrument
supports eight markers. Marker information is stored in measurement files
and setup files and is displayed when either file type is recalled. Pressing the
Marker main menu key displays the marker menu.
Overview of Markers
• Frequency measurements (Return Loss, Cable Loss, and VSWR) have
common markers. Distance measurements (DTF Return Loss and DTF
VSWR) also have common markers.
• Press and hold on a marker to select and display the amplitude and
frequency/distance information. Drag a marker to move it.
• The selected marker displays a vertical red line and has its value
displayed in the highlighted row in the marker table. Select a marker
to edit by using the touchscreen or the Select (1-8) marker button.
• Selected markers can be quickly dragged to a new location using the
touchscreen or can be moved by double tapping on the display, by using
the Arrow keys, or by using the rotary knob.
• Markers can be selected (and moved) outside of the Marker menu. Tap
on a marker (thin green vertical line) to make it active and ready for
moving.
• Markers set beyond the current frequency or distance range are
displayed at either the left or right of the graph.
• If the frequency (F1 or F2) or distance (D1 and D2) parameters are
moved inside a current marker location, then the out of range
(---> or <----) indicator is displayed, and marker values in the Table are
blanked (--). See Figure 3-23 for an example of markers beyond the
current span.
• Markers beyond the current span cannot be edited.
• Marker location and type are stored when the marker is turned off.
• Marker Preset restores the markers to their default state. All markers
are turned off except for Marker 1 which is set to the middle of the
sweep. Previous marker information is not saved.
