Behavior
Waveform cursors can measure parameters on the same waveform or on different waveforms. The
cursors measure vertical parameters (typically volts) and horizontal parameters (typically time or
frequency) simultaneously. An X identifies the cursor location at the point where the cursors
intersect the waveform.
The cursor readouts appear on the graticule when a control window is open. When the control
windows are closed, the readouts appear on the right side of the screen.
One ∆ (delta) shows the voltage difference between the two cursors while the other ∆ shows the
time (or frequency) difference between the cursor values.
Screen Cursors
To Use
To select screen cursors, click Screen in one of the cursor control windows or click Screen from
the Cursor Type submenu of the Cursors menu. Use the multipurpose knobs to move the cursors.
Use the Cursor Source Channel Selector tabs to select the waveforms that you want to measure.
Behavior
Use screen cursors to indicate an arbitrary X and Y position in the waveform display area
represented by the intersection of a vertical and horizontal cursor line. Screen cursors measure
both vertical parameters (typically volts) and horizontal parameters (typically time or frequency).
Readouts display measurement parameters for both cursors. Vertical readouts display voltage
values for each cursor with respect to the zero reference point and with respect to each other.
Horizontal readouts display time or frequency values for each cursor with respect to the trigger
point and with respect to each other.
Cursor Modes
To Use
To select the cursor mode, click either the Indep (independent) or Tracking button in the Cursor
Setup control window.
Behavior
In Independent mode, you can move one cursor at a time using the multipurpose knobs.
In Tracking mode, moving Cursor 1 moves Cursor 2 in tandem so that Cursor 2 will always
remain a fixed distance (time or voltage) from the Cursor 1. However, moving Cursor 2 does not
move Cursor 1.
Select the cursor mode directly from the Cursors menu Cursor Mode submenu.
