CURSORS
Description:
Cursors are on-screen measuring lines. They can be moved using the TRACK
and ∆ controls. Cursors can be positioned on signal details of interest and can be
used for accurate measurements.
Basically there are two types of cursors: vertical lines (||) called time cursors and
horizontal lines (=) called volt cursors. A simultaneous display of both cursor
types (#) is possible.
If the acquisition length in digital mode is more than 10 horizontal screen
divisions, it is possible to position the cursors horizontally along the complete
acquisition. When a cursor that is visible on the screen is moved outside the
screen, it will drag the trace with it. This means that the X POSition is changed. A
bar graph shows the display window and cursor positions in relation to the total
acquisition length. The cursors are trace oriented rather than display oriented.
The acquisition length can be selected via the TB MODE menu.
The readout of the delta between the cursor lines is shown in the cursor display
area (upper part of the CRT viewing area). In analog mode the display can be in
voltage or time, and is in digital mode in voltage and
time at the same time. In this
way cursors can be used for accurate on-screen measurements without using the
graticule. Additional readout information can be selected under the READOUT
softkey. For details see the CURSOR READOUT function.
The cursors are activated via the menus under the CURSORS menu key. The
structure of the menu is shown in Appendix B.
Activating the cursors is made with the ’CURSORS on/off’ menu selection.
