Measuring Waveforms

There are three cursor types: horizontal bar, vertical bar, and paired

(see Figure 3–61).

Horizontal Bar Cursors Vertical Bar Cursors

Paired Cursors

Figure 3–61: Cursor Types

Horizontal bar cursors measure vertical parameters (typically volts).

Vertical bar cursors measure horizontal parameters (typically time or frequency).

Paired cursors measure both vertical parameters (typically volts) and horizontal

parameters (typically time) simultaneously.

Look at Figure 3–61. Note that each of the two paired cursors has a long vertical

bar paired with an X. The Xs measures vertical parameters (typically volts); the

long vertical bars measure horizontal parameters (typically time or frequency).

(See Cursor Readouts on page 3–128 for more information.)

NOTE. When cursors measure certain math waveforms, the measurement may not

be of time, frequency, or voltage. Cursor measurement of those math waveforms

that are not of time, frequency, or voltage is described in Waveform Math, which

begins on page 3–188.

There are two cursor modes: independent and tracking. (See Figure 3–62.)

In independent mode, you move only one cursor at a time using the general

purpose knob. The active, or selected, cursor is a solid line. Press SELECT to

change which cursor is selected.
