 °: in the measurement results, A->X, B->X and △X are expressed in degree.
At this point, A->X, B->X and △X will change to “0°”, “360°” and “360°”
respectively when you press SetCursor, no matter where cursor A and
cursor B are currently located. At the same time, two cursor lines
(unmovable) appear on the screen as the reference positions.
 %: in the measurement results, A->X, B->X and △X are expressed in
percentage.
At this point, A->X, B->X and △X will change to “0%”, “100%” and “100%”
respectively when you press SetCursor, no matter where cursor A and B
are currently located. At the same time, two cursor lines (unmovable)
appear on the screen as the reference positions.
Note: When the display mode is set to “Y”, the Time Unit menu will be hidden
automatically and cannot be set.
When the display mode is “Y” or “X-Y”, press Vertical Unit to select “Source

 Source Unit: when this unit is selected, in the measurement results, the
units of A->Y, B->Y and △Y will be automatically set to the unit of the
current source.
 %: when this unit is selected, in the measurement results, A->Y, B->Y and
△X are expressed in percentage. At this point, A->Y, B->Y and △X will
change to “0%”, “100%” and “100%” respectively when you press
SetCursor, no matter where cursor A and B are currently located. At the
same time, two cursor lines (unmovable) appear on the screen as the

and cannot be changed; you can only set the X axis unit. Press Time Unit
softkey to select “s”, “Hz”, “°” or “%”.
 s: in the measurement results, CurA, CurB and △X denote time.
 Hz: in the measurement results, CurA, CurB and △X denote frequency.
 °: in the measurement results, CurA, CurB and △X are expressed in degree.
