F4 key "ZOOM"
By pressing the F4 key "ZOOM* the viewed window can be
varied for high-resolution
display,
in steps up to 1
measurement point per pixel of the screen graphics. The
window thus created can be moved over the total number
of captured image points. The portion of the overall signal
image
currently
being viewed
in the zoom
window
is
indicated in the bottom panel in reversed colors. A fast
switching of the ZOOM window is possible by pushing the
HOME, END, PgUp or PgDn key. Aninverse marker indicates
the position of the actual ZOOM
window.
F5 key "WINDOW" or "C-MOVE"
The F5 key is used to toggle the scroll function between 2
modes. In WINDOW
mode (only black signal curves) the
evaluation window is moved while the cursors remain at
the same positions on the signal. The non active cursor
remains at its position. In C-MOVE mode the active cursor
is moved on the signal; when the edge of the window is
reached, the window
is shifted. This feature permits bit-
by-bit evaluation with maximum
resolution. The window
can be shifted rapidly using the HOME/END
and PgUp/
PgDn keys. The currently active mode is shown in the
OPTIONS window on the lower right.
CTRL + Cursor "left" / "right"
If the CTRL or STRG key is held depressed when striking
the "cursor
left" and
"cursor
right" keys, the cursor
is
moved faster.
SHIFT + F2 key "READ"
For reading in data without the scalation window; see
page 12.
SHIFT + F3 key "12>34"
Copies channels 1+2 to channels 3+4, which then function
as reference channels.
SHIFT + F4 key "ZOOM"
Reduces the ZOOM factor by one step.
SHIFT + F5 key "SPLIT"
This function results in simultaneous display of all channels
in use, with overlaps being separated. Depending on the
number of channels that need to be displayed, the screen
is automatically
divided
up into 2, 4 or 8 fields.
For
example, if there are only 3 displayable channels, then the
fourth window remains empty. In SPLIT mode all cursor
functions are also available. Each channel can be selected
with "SWAP". Here too, the conditions are met for optimal
signal evaluation. Pressing the keys SHIFT+F5 again exits
SPLIT made.
