To make cursor measurements
The following steps guide you through the front-panel Cursors key. You can
use the cursors to make custom voltage or time measurements on the signal.
Examples of custom measurements include rise time measurements from
reference levels other than 10-90%, frequency and width measurements from
levels other than 50%, channel-to-channel delay measurements, and voltage
measurements. With Option 005 in your oscilloscope, the cursors can also be
calibrated in IRE units.
1
Connect a video signal to the oscilloscope and obtain a stable display.

.
A softkey menu appears with six softkey choices. Four of the softkeys are
cursor functions.
Source
Selects a channel for the voltage cursor measurements. The cursor is
calibrated to the Volts/div of the selected channel.
Active Cursor
There are four cursor choices:
V1
and
V2
are voltage
cursors,
t1
and
t2
are time cursors. Use the knob below the
Cursors
key to move the cursors. To move the cursors together,
press the
V1
and
V2
softkeys simultaneously or press the
t1
and t
2
softkeys simultaneously.
Clear Cursors
Erases the cursor readings and removes the cursors from the
display.
TV graticule
With the TV graticule ON, the voltage cursors are calibrated in IRE units.
With the TV graticule OFF, the voltage cursors are calibrated in volts.
IRE units only make sense if the video signal is scaled properly, such as after a
video autoscale.
