• Press the Cursors softkey; then, turn the Entry knob.
The X1 X2 linked and Y1 Y2 linked selections let you adjust both cursors at

useful, for example, for checking pulse width variations in a pulse train.
The currently selected cursor(s) display brighter than the other cursors.
6 To change the cursor units, press the Units softkey.
In the Cursor Units Menu:
You can press the XUnits softkey to select:
• Seconds (s).
• Hz (1/s).
• Phase (°) — when selected, use the Use X Cursors softkey to set the
current X1 location as 0 degrees and the current X2 location as 360
degrees.
• Ratio (%) — when selected, use the Use X Cursors softkey to set the
current X1 location as 0% and the current X2 location as 100%.
You can press the YUnits softkey to select:
• Base — the same units used for the source waveform.
• Ratio (%) — when selected, use the Use YCursors softkey to set the
current Y1 location as 0% and the current Y2 location as 100%.
For phase or ratio units, once the 0 and 360 degree or 0 and 100%
locations are set, adjusting cursors will display measurements relative
to the set locations.
