the 5 (for single cursors) or 2.5 and 7.5 (for relative cursors) division marks of the target trace and
adjusts the source cursors accordingly.
Note: Horizontal Relative cursors are initially placed one on the negative side of the X-Axis
(marked by a
⬇
down arrow) and one on the positive side (marked by an
⬆
up arrow). If you
move the negative cursor to the right of the positive cursor, or the positive cursor to the left of
the negative cursor, the delta will be shown in negative increments.
Use the Position data entry controls on the Standard Cursors dialog to place cursors precisely.
Standard Cursors Dialog
These controls can be used instead of the front panel controls to set cursors or to refine the cursor
position. Access the dialog by choosing Cursors > Cursors Setup from the menu bar.
Cursors On displays or hide cursor lines. When first checked, the last selected cursor type is
displayed.
Cursor Type buttons select the type of cursor displayed on the grid.
The Show controls determine which values are shown in the readout, particularly when using relative
cursors:
l
Absolute shows specific voltages for the two cursor locations.
l
Delta shows the difference between the specific voltages at the cursor locations.
l
Abs+Delta shows both the absolute and delta readouts.
l
Slope (Horizontal Relative only) shows the slope of the waveform between the cursor
locations.
The Position controls at the right-side of the Standard Cursors dialog display the current cursor
location and can be used to set a new location. The options available depend on the Cursor Type
settings.
l
X 1 (negative) and X 2 (positive) sets time from the zero point.
l
Y 1 (negative) and Y 2 (positive) sets number of divisions from the zero level. May be a fraction
of a division.
l
Track locks cursor lines so they move together, maintaining their same relative distance from
each other.
