Yes, you can. Cursors are useful tools for making accurate measurements in Moku instruments. Cursors are available in the Spectrum Analyzer, Frequency Response Analyzer, and Oscilloscope (including any embedded Oscilloscopes in other instruments). 

Adding cursors

There are three ways to add cursors to the active trace. First, click a trace to make it active, then:

1. Right click to select a cursor option (x- and y- axis options are available depending on the instrument).
2. Click or drag out from the cursor button in the bottom-left
3. Use the keyboard shortcuts:
   1. Tracking cursor: Ctrl + left mouse button
   2. Horizontal axis cursor: Shift + left mouse button
   3. Vertical axis cursor: Ctrl + Shift + left mouse button

To see all keyboard shortcuts, click "Help" under the main menu or press Ctrl + H. 

Moving cursors

Click to select the cursor then drag to move it. You can also type the value directly into the cursor's label box to track a specific x- or y-axis value. 

Removing cursors

To remove cursors, right click on the cursor you wish to delete and then select "Remove." You can also right click anywhere on the screen and select "Remove all cursors."
