Measuring Waveforms

There are three cursor types: horizontal bar, vertical bar, and paired
(see Figure 3–65).
Horizontal Bar Cursors Vertical Bar Cursors
Paired Cursors
Figure 3–65: 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 3–65. 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 3–140 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 3–206.
There are two cursor modes: independent and tracking. (See Figure 3–66.)
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.
