Cursors Using XY Display Format
Access this control window from the Cursors menu Cursor Setup command. The Cursor Setup control
window varies depending on the display format.
Overview
Use these controls to set the cursor parameters when you are using XY display format.
To Use
Select the readout format from the XY Readout drop-down list.
Behavior
When you are using XY display format, only Waveform and Screen cursors are available. If you
change the display format to XY when H Bar cursors are enabled, the cursor type will change to
Screen. In normal acquisition mode, changing the display format to XY when V Bar cursors are
enabled, changes the cursor type to Waveform. In FastAcq acquisition mode, changing the display
format to XY when V Bar cursors are enabled, changes the cursor type to Screen.
If you change the display format from XY to YT when Screen cursors are enabled, the cursor type
is changed to H Bars.
XY Cursor Readouts only appear when you are using XY display format. Rectangular XY
readouts are the default.

display nine rectangular readouts (
