automatically selected under Region and cannot be modified.
When the delayed sweep function is enabled, the screen is divided into two
⚫
regions: main time base and zoomed time base. Click Region continuously
to select "Main" or "Zoom".
When "Main" is selected, the cursor is displayed in the main time base
➢
region, and you can measure the parameters in the main time base
region.
When "Zoom" is selected, the cursor is displayed in the zoomed time
➢
base region, and you can measure the parameters in the zoomed time
base region.
5. Set the Horizontal/Vertical Measurement Unit
When "X" is selected under Select, you can set the horizontal measurement

unit. When the source can be Math1-Math4, this menu is grayed out and
disabled.
Click More → Hori. Unit to select the horizontal measurement unit. 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 reference position for the phase
according to your needs. After adjusting X Cursor to a desired position,
click 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 reference position for the ratio
according to your needs. After adjusting X Cursor to a desired position,
