To make cursor measurements

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.
Connect a video signal to the oscilloscope and obtain a stable 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.
