6.2 Measurement Using Scope

When the instrument has been correctly setup and configured, make sure that Scope has been selected, as shown in Figure 6-9.

The scope mode allows that measurement be ran over a short amount of time. In order to maximize the amount of data, use the following measurement setup: (see Figure 6-10).

  • Time/div: 200 ms/
  • Points: 512k
  • Trigger: Scope Run Button
  • Mode: Single
  • Slope: Rising Edge

Next, make sure that the “Ranges…” is setup to Auto, as shown in Figure 6-11.
