NOTE
If one of the three menu items (
AX, BX, and AX BX) is selected; or one of the three menu
items (
AY, BY, and AY BY) is selected; you can press down the multifunction knob
continuously to switch among the three items.
4. Set the Horizontal/Vertical Measurement Unit
- When "X-X" is selected, you can set the horizontal measurement unit. When the
source is set to Math1-Math4, this menu is grayed out and disabled.
Press
More > Hori. Unit, then rotate the multifunction knob to select the
horizontal measurement unit, and then press down the knob to select it. You
can also press Hori. Unit continuously or enable the touch screen to select it.
The available units include "s", "Hz", "Degree(°)", and "Percent(%)".
- s: measures the time value at X Cursor (taking the trigger position as
reference). The measurement results include AX, BX, ∆X, and 1/∆X. Wherein,
AX, BX, and ∆X all indicate time, and 1/∆X indicates frequency.
- Hz: measures the frequency value at X Cursor (taking the trigger position as
reference). The measurement results include AX, BX, ∆X, and 1/∆X. Wherein,
AX, BX, and ∆X all indicate frequency, and 1/∆X indicates time.
- Degree(°): measures the phase value at X Cursor. The measurement results
include AX, BX, and ∆X, and they are all expressed in degree.
This oscilloscope allows you to set the phase reference position 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 ∆X, and they are all expressed in percentage.
This oscilloscope allows you to set the ratio reference position 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
