Description
The ratio of the negative pulse width to the signal period expressed as a percentage. The duty
cycle is measured on the first cycle in the waveform or gated region.
The time required to complete the first cycle in a waveform or gated region. Period is the reciprocal
of frequency and is measured in seconds.
The frequency of the first cycle in a waveform or gated region. Frequency is the reciprocal of the
period; it is measured in Hertz (Hz) where one Hz is one cycle per second.
The time between the mid reference (default 50%) amplitude point of two different waveforms.
Description
The area over the entire waveform or gated region in volt-seconds. Area measured above ground is
positive; area measured below ground is negative.
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 while the area below the
common reference point is negative.
The amount of time that one waveform leads or lags another waveform, expressed in degrees
where 360° contains one waveform cycle.
The duration of a burst (a series of transient events) and is measured over the entire waveform
or gated region.
Description
Displays the number of waveforms that have contributed to the histogram.
Displays the number of points in or on the histogram box.
Displays the number of points in the largest bin of the histogram.
Displays the middle point of the histogram box. Half of all acquired points within or on the histogram
box are less than this value and half are greater than this value.
Displays the voltage of the highest nonzero bin in vertical histograms or the time of the rightmost
nonzero bin in the horizontal histograms.
Displays the voltage of the lowest nonzero bin in vertical histograms or the time of the leftmost
nonzero bin in the horizontal histograms.
Displays the peak-to-peak value of the histogram. Vertical histograms display the voltage of the
highest nonzero bin minus the voltage of the lowest nonzero bin. Horizontal histograms display the
time of the rightmost nonzero bin minus the time of the leftmost nonzero bin.
Measures the average of all acquired points within or on the histogram box.
Measures the standard deviation (Root Mean Square (RMS) deviation) of all acquired points within
or on the histogram box.
Displays the percentage of points in the histogram that are within one standard deviation of the
histogram mean.
