To Make Cursor Measurements - HP 54616B User And Service Manual

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