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
The coordinate Rulers allow the amplitude 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.
There are three types of measurement rulers: the vertical Time Ruler, the horizontal
Signal Ruler, and the vertical Angle Ruler.
Tap the Ruler Activator in the lower left corner of the grid and drag it across the
screen to the desired position. A Time Ruler is generated.
Tap the Ruler Activator in the lower right corner of the grid and drag it across the
screen to the desired position. An Angle Ruler is generated.
The two angle rulers are positioned to mark the start and end of a cycle. By default,
the start and end angle values are 0° and 720°, which can be configured in the Phase
Setting box.
The Signal Ruler can be generated in the similar way by tapping the Ruler
Activator in the upper right corner and dragging it downwards.
When dragging the Measurement Rulers, 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.
