Zooming a Single Channel
Touch the channel trace label for a displayed channel.
Touch the Zoom button at the bottom of the Cx
Vertical Adjust dialog. A zoom trace of the selected
channel (one of Z1 to Z4) is created on a separate
grid.
Vary the zoom degree by touching Zx trace label (just
created). The setup dialog for the zoom trace opens.
It shows the current horizontal and vertical zoom
factors.
If you want to increase or decrease horizontal or
vertical zoom in small increments, touch the
Var.
checkbox to enable variable zooming. Now, with each
touch of the zoom control buttons, the degree of
magnification changes by a small increment.
You can zoom in or out using large, standard
increments when touching zoom control buttons by
leaving the
Var. checkbox unchecked. Set exact
horizontal or vertical zoom factors by touching inside
the Horizontal
Scale/div field and providing a time-
per-div value (with the pop-up numeric keypad). Now,
touch inside the Vertical
Scale/div field and enter a
value.
Reset the zoom to x1 magnification by touching Reset
Zoom in the dialog. Turn off the zoom trace by
touching the QuickZoom button or un-checking the
Trace On checkbox.
