10 To change the marker measurement units, select Units....
In the Marker Units dialog box:
From the X Units drop-down list, you can select:
• Seconds (s).
• Hz (1/s).
• Phase (°) — When selected, select Use X Markers As 360° to set the current X1 
location as 0 degrees and the current X2 location as 360 degrees.
• Ratio (%) — When selected, select Use X Markers as 100% to set the current X1 
location as 0% and the current X2 location as 100%.
From the Y Units drop-down list, you can select:
• Base — The Y marker units are the same as used for the source waveform.
• Ratio (%) — When selected, select Use Y Markers as 100% 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 markers will display measurements relative to the set locations.
11 Select the Global X Markers check box to, when there are multiple grids, enable 
or disable the placement of X markers in all grids. When disabled, X markers 
appear in the same grid as the source waveform.
