Measurement cursors (Waveform display only)

The measurement cursors are available only for the Waveform display. The
cursors enable you to accurately measure desired portions of the displayed
waveform.

Cursor types

There are two types of measurement cursors:

■

Time:

There are two cursors for measuring time along the horizontal axis of

the waveform.

■

Voltage:

There are two cursors for measuring voltage levels along the

vertical axis of the waveform. You can set the units for the voltage cursors to
be either millivolts or percentage. When the cursors units are set to
percentage, you can set the current cursor position to be the 100% level.

The cursor readouts display the current position of each cursor and also the
difference between them.

To display and adjust the

cursors

Perform the following steps to display and adjust the measurement cursors in the
Waveform display:

1.

Select which cursors to display and set the cursor units:

a.

Press and hold the

CURSOR

button to open the Cursor pop-up menu.

b.

Use the arrow keys to set the

Cursor Style

to one of the following:

■

Voltage:

Displays only the two voltage cursors.

■

Time:

Displays only the two time cursors.

■

V Time:

Displays both the voltage and time cursors.

a.

For voltage cursors only, use the arrow keys to set the

Voltage Cursor

Units

to one of the following:

■

mV:

Sets the cursor units to millivolts.

■

%:

Sets the cursors units to percentage.
