HOW TO USE THE INSTRUMENT 4 - 45

CURSORS ON/OFF

There are two sets of cursors : amplitude cursors and time cursors. Amplitude cursors are two horizontal lines, and Time cursors are two vertical lines. The dashed lines are referred to as reference cursors and the dotted lines are referred to as delta (Δ) cursors.

Cursor measurements can be made in both operating modes of the instrument. Amplitude and time cursors can be displayed at the same time.

-Press the ANALOG key to set the scope in mode.

-Press the CURSORS key to enter the cursors menu.

The menu is now displayed. Time cursors (’’) are selected by default. In the digital mode, two ’x’s mark the actual measuring point where the cursors intersect with the signal. In the analog mode these ’x’ indicators are not available.

CURSORS TIME

Using the TRACK and Δ controls, you can adjust the position of the cursors. The time and amplitude difference between the cursors is read in the top of the screen. Cursor readout parameters can be

changed and are selected via theCURSORS ’READ OUT’ softkey.
