➢ Degree(°): measures the phase value at X Cursor. The measurement
results include AX, BX, and â–³X, and they are all expressed in degree.
This oscilloscope allows you to set the reference position for the phase
according to your needs. After adjusting X Cursor to a desired position,
press Set Reference to take the current cursor position as the
reference. The current positions of Cursor A and Cursor B are
respectively defined as "0°" and "360°". Meanwhile, two vertical
cursors (in blue) that cannot be moved are displayed on the screen as
the phase reference position (the phase position at "0°" and "360°" are
respectively marked by a solid line and a dotted line). Before you set
manually, the oscilloscope adopts the default phase reference position.
➢ Percent(%): measures ratio at X Cursor. The measurement results
include AX, BX, and â–³X, and they are all expressed in percentage. This
oscilloscope allows you to set the reference position for the ratio
according to your needs. After adjusting X Cursor to a desired position,
press Set Reference to take the current cursor position as the
reference. The current positions of Cursor A and Cursor B are
respectively defined as "0%" and "100%". Meanwhile, two cursors (in
blue) that cannot be moved are displayed on the screen as the ratio
reference position (the ratio position at "0%" and "100%" are
respectively marked by a solid line and a dotted line). Before you set
manually, the oscilloscope adopts the default ratio reference position.
âš« When "Y" is selected under Select, you can set the vertical measurement
unit. When the source can be Math1-Math4, this menu is grayed out and
disabled.
Press More → Vert. Unit, and rotate the multifunction knob to select
the vertical measurement unit. Then press down the knob to select it. You
can also press Vert. Unit continuously or enable the touch screen to select it.
The available units include "Source" and "Percent(%)".
➢ Source: measures the amplitude at Y Cursor (taking the channel
ground point as the reference). The measurement results include AY,
BY, and â–³Y (its unit is consistent with that of the current source).
➢ Percent(%): measures ratio at Y Cursor. The measurement results
include AY, BY, and â–³Y, and they are all expressed in percentage.
This oscilloscope allows you to set the reference position for the ratio
according to your needs. After adjusting Y Cursor to a desired position,
press Set Reference to take the current cursor position as the
reference. The current positions of Cursor A and Cursor B are
respectively defined as "0%" and "100%". Meanwhile, two cursors (in
blue) that cannot be moved are displayed on the screen as the ratio
reference position (the ratio position at "0%" and "100%" are
respectively marked by a solid line and a dotted line). Before you set
manually, the oscilloscope adopts the default ratio reference position.
