Cursor Types; Apply And Position Cursors - Teledyne HDO9000 Operator's Manual

Cursor Types

Horizontal (Time) cursors intersect a point on the horizontal axis.
Horizontal Abs displays a single, dashed, vertical line. The readout shows the absolute value at
l
the cursor location.
Horizontal Rel displays two, dashed, vertical lines. The readout may be in absolute values or a
l
delta of the two points, depending on the Show option selected.
Vertical (Amplitude) cursors intersect a point on the vertical axis.
Vertical Abs displays a dashed, horizontal line. The readout shows the absolute value at the
l
cursor location.
Vertical Rel displays two dashed, horizontal lines. As with Horizontal Relative cursors, the
l
readout may show absolute values or a delta.
The Both Rel(ative) option places both Vertical and Horizontal relative cursors together.

Apply and Position Cursors

Apply Cursors
To turn on cursors, either:
From the menu bar, choose Cursors and select the desired cursor type from the drop-down list.
l
On the front panel, press the Cursor Type button repeatedly to cycle through all the cursor
l
types. Stop when the desired type is displayed.
Note: There must be a waveform on the grid for cursors to execute, although acquisition may
be in process or stopped when you turn them on.
To turn off cursors, choose Cursors > Off, or continue cycling the Cursor Type button until they
disappear.
Position Cursors
The easiest way to reposition a cursor is to drag-and-drop the cursor marker to a new position.
Indicators outside the grid show to which trace the cursor belongs when you have multiple traces on
one grid.
Alternatively, turn the knob. If both vertical and horizontal cursors are turned on, push the knob until
the correct line is selected, then turn to move it. When there are multiple traces each with its own
cursors on the same grid, bring the desired trace to the foreground by touching the trace or its
descriptor box. The Cursors knob will only operate on the foreground trace.
If Horizontal cursors are applied to a source trace but do not appear on its dependent traces (e.g., a
zoom) because of differences in scale, you can drag-and-drop the cursor readout from below the
Timebase descriptor box onto the target trace or its descriptor box. This applies the same cursors at
