Drag the horizontal grid lines to set the vertical shift on channel A (or channel B, if
channel A is turned off).
The grid position is adjusted to keep the ground of channel A (or channel B, if
channel A is turned off) on one of the horizontal grid lines.
The voltage of each horizontal grid line is displayed (channel A on the left, channel B
on the right).
The trigger event is marked with the red triangle located in the bottom of the screen. If
the trigger event occured before the displayed waveform, the arrow pointing left is
drawn. If the trigger event occured after the displayed waveform the arrow pointing
right is drawn.
WARNING: The trigger mark position can differ slightly (especially when using
a fast timebase) from the real position of the trigger event.
The horizontal dotted line of the appropriate channel color indicates the ground
position of the appropriate channel. Drag this line to set the vertical shift of the
appropriate channel. If the ground position is off of the screen, the arrow with the
ground symbol is displayed on the top or bottom of the main window. Drag this arrow
to get the ground position back onto the screen.
Two vertical and two horizontal cursors can be activated. Vertical cursors have red
(cursor 1) and blue (cursor 2) color by default. Horizontal cursors have red (cursor 1)
and blue (cursor 2) color by default as well.
TIP: The cursors color can be changed in the main menu.
You can move a cursor by dragging it.
The waveform is drawn using the channel color. The default channel colors are as
follows: Channel A green, channel B yellow, virtual channel (the one used for
display of function result) C is light blue and channel D is orange.
TIP: The channel colors can be changed in the main menu.
The threshold voltage mark is located on the left. You can change the threshold
voltage by dragging it.
TIP: If the memory size used is larger than 64k, the quickview is displayed above
the oscilloscope screen. Use the quickview to select the 64k long part of the
memory that can be displayed in the oscilloscope screen.
4.2.2. Quickview
If the memory size used is larger than 64k, the quickview is displayed above the
oscilloscope screen.
