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. See figures 2-11
through 2-16 for examples of custom measurements.
