Measurement
Description
Area
Area measurement is a voltage over time measurement. It 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 over the first cycle in the waveform
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.

The Power Measurements panel (optional)
The Power panel lists the power-related measurements that you can add to the Results bar. Power measurements include power quality,
switching loss, harmonics, ripple, modulation, and safe operating area. The Power Measurements panel is shown only if you have
purchased and installed the Power Measurement and Analysis option.
To open the Power Measurements panel:
1. Tap the Measure button.
2. Tap the Power measurements panel.
To add a measurement to the Results bar:
1. Tap a measurement.
2. Tap Add.

Measurement
Description
Power Quality
Measures the Frequency, RMS values of the voltage and current, Crest Factors of the
voltage and current, Real Power, Reactive Power, Apparent Power, Power Factor, and
Phase Angle of the AC signal.
Switching Loss
Measures power loss and energy loss across the acquired waveform, including turn-on,
turn-off, conduction, and total loss.
Harmonics
Measures the signal amplitudes at the fundamental line frequency and its harmonics.
Measures the RMS amplitude and Total Harmonic Distortion of the signal. Plots the
Harmonics Bar Graph.
Ripple
Measures ripple and statistics for the AC components of the acquired waveform.
Modulation
Measures the modulation value across the acquired waveform.
Safe Operating Area
Measures the switching device-under-test's voltage and current. Also, performs a mask test
of the X-Y signal relative to the graphical X-Y description of the device specification limits.
