This sub-menu lets you control how markers are displayed on the graph. You can enable up to four markers and a delta marker.

Markers are available for all graph types. The markers allow individual points to be selected on the graph and tracked using the marker area underneath of the trace graticule. All measurements support up to 4 individual markers and a single delta.

To add a Marker,

  1. Select any modulation schemes from the Modulation menu.
  2. Click Graphics tab.
  3. Click Markers menu or right-click on the trace.
  4. Select the marker you want to add, and select Enable. This will turn the marker on and move the marker to the location clicked on the trace.

Moving a Marker

Markers can be moved in several ways.

  • Left and Right Arrows — When a marker is selected, pressing the left and right buttons on your keyboard will move the marker a single sample backwards or forwards from the current marker position.
  • Page Up/Down — When a marker is selected, pressing the page up or down buttons on your keyboard will move the marker 10 samples backwards or forwards from the current marker position.
  • Using the Mouse — You can move a marker using the mouse, by clicking and dragging the marker to the desired location. For non polar plots, the marker will be moved to the closest sample in the X domain to the current mouse position. In a polar plot, the marker will be moved to the nearest sample to the current mouse position.
  • Move Marker to Here — If you right-click on the trace graticule, within the marker menu for the desired marker, you can select Move marker to here. This will move the marker to the selected location.

Marker Controls

As the basic marker functions, RFmx Waveform Creator supports specific marker functions that can be used to find particular artifacts within the trace. These are as follows:

  • All Markers Off – Use this function to turn off all markers that are currently enabled.
  • Enable – Use this function to turn a marker on or off. The first time a marker is enabled, it is automatically moved to the first location you right clicked.
  • Track Peak – Enables a marker and automatically moves it to the highest Y value in the trace. When you select this option the marker automatically moves whenever the trace data is regenerated.
  • Peak Find – Moves the marker to the highest value on the trace.
  • Last Peak – Moves the marker to the next highest peak to the current marker position.
  • Next Peak – Moves the marker to the next lowest peak to the current marker position.
  • Peak Right – Moves the marker to the next peak to the right of the current marker position.
  • Peak Left – Moves the marker to the next peak to the left of the current marker position.
  • Delta Marker – The delta marker is manipulated in exactly the same way as normal markers. As the delta marker reports values relative to normal markers you can only display a delta marker if a normal marker is enabled.

When a delta marker is enabled, the marker table is updated with delta values. The following image depicts the Graphics tab with all markers enabled. As the delta marker does not report its own values, but instead the differences between its position and other markers, the Delta marker can only be enabled if you have one or more standard markers enabled.
