The zooming function allows you to change the size and position of a signal during or
after capturing a waveform to examine. It does not change the stored data, only the
way it displays.
The X-axis and Y-axis can be zoomed using your fingertips. The waveform can be
zoomed during or after capturing the signal.
Measurement Rulers
In the coordinate grid, there are two types of
measurement rulers
, which allow the
voltage and time duration of a waveform to be measured precisely. They are useful
when determining signal characteristics such as amplitude at specific points, the cycle
time (duration) and frequency.
The vertical
Time Ruler
- Tap the
Ruler Activator
in the bottom left corner of the grid
and drag it across the screen to the desired position. A
Time Ruler
is generated.
The horizontal
Voltage Ruler
-
The
Voltage Ruler
can be generated in the similar way
by clicking the
Ruler Activator
in the top right corner and dragging it downwards.
When Measurement Rulers are generated, a
Ruler Table
showing time and voltage
values for the corresponding channels will be displayed. The
Delta
icon refers to the
absolute difference between the values of the rulers, which can be locked by tapping
the
Lock
icon. Tap the
X
button in the upper right corner of the ruler table to delete all
rulers.
