CURSORS

Description:

Cursors are on-screen measuring lines. They can be moved using the TRACK and Δ 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.
