Area measurements

Measurement Description

Area A voltage over

time measurement. The measurement returns the area over the entire

waveform or gated region in volt-seconds. Area measured above ground is positive;

area measured below ground is negative.

Cycle Area A voltage over time measurement. The measurement is the area o ver the ﬁrst cycle

in the wavef

orm or the ﬁrst cycle in the gated region expressed in volt-seconds. The

area above the common reference point is positive, and the area below the common

reference point is negative.

Taking a measurement on just a part of the waveform (Gating)

Gating sets the automatic measurements to use only a speciﬁed part of a waveform for the measurements. The Gating

function applies to all channels and all m ea surements (in other words, you cannot set a different gating region for individual

measurements or different channels).

1. Push Measure.

2. Push the Gating side-menu button.

3. Use the Multip urpose knob to select and click the area of the waveform to use for taking m easurements (Off (Full

Record), Screen, Between Cursors)

If selecting Between Cursors,usethe

Multipurpose knob to select and move the

gatin

g cursors to mark the waveform area

to use for automatic measurements.
