7.3.5.2 Main View Section
The main view section screen displays as a coordinate grid with X-axis and Y-axis,
representing the duration and amplitude level respectively.
Channel Selection
In the main view section, a channel has two conditions: selected and unselected. A
channel must be selected in order for the waveform to be movement, to use the
zoom-in or to add measurement rulers.
To select and unselect the channel
1. Tap the zero baseline marker or the Y-axis (the line thickens when selected).
2. Tap the zero baseline marker or the Y-axis again to exit the channel selection.
Waveform Zooming
The zooming function allows you to change the size and position of a signal during
or after capturing a waveform to examine it in greater details. 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 Ruler
In the coordinate grid, there are two types of measurement rulers, which allow the
amplitude and duration of a waveform to be measured precisely. They are useful
when determining signal characteristics such as amplitude at specific points, and the
cycle time (duration).
The vertical Time 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.
The horizontal Signal Ruler - The Signal Ruler can be generated in the similar way
by clicking 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 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.
