CARea (cycle ar
ea) measures the voltage over time. In other words, it measures, in
volt-seconds, the area over the first cycle in the waveform or the first cycle in the
gated region. The area measured above t he common reference point is positive,
while the area below the common reference point is negative. This measurement
is available only on DPO models.
CMEan (cycle mean) measures the a rithmetic mea n over the first cycle in the
waveform or the first cycle in the gated region. This measurement is available
onlyonDPOmodels.
CRMs (cycle rms) measures the true Root Mean Square voltage over the first
cycle in the waveform or the first cycle in the gated region. This measurement is
availabl
e only on DPO models.
DELay measures the time between the middle reference (default = 50%) amplitude
point of
the source waveform and the destination waveform. This measurement is
available only on DPO models.
FALL me
asures the time taken for the falling edge of the first pulse in the
waveform or gated region to fall from a high reference value (default is 90%) to
a low reference value (default is 10%). This measurement is available only on
DPO models.
FREQuency measures the first cycle in the waveform or gated region. Frequency
is the reciprocal of the period and is measured in hertz (Hz), where 1 Hz = 1
cycle per second.
HIGH measures the High reference (100% level, sometimes called Topline) of a
waveform. This measurement is available only on DPO models.
LOW measures the Low reference (0% level, sometimes called Baseline) of a
waveform. This measurement is available only on DPO models.
MAXimum finds the maximum amplitude. This value is the most positive peak
voltage found. It is measured over the entire waveform or gated region. This
measurement is available only on DPO models.
MEAN amplitude measurement finds the arithmetic mean over the entire waveform
or gated region. This measurement is available only on DPO models.
MINImum finds the minimum amplitude. This value is typically the most negative
peak voltage. It is measured over the entire waveform or gated region. This
measurement is available only on DPO models.
NDUty (negative duty cycle) is the ratio of the negative pulse width to the signal
period, express ed as a percentage. The duty cycle is measured on the first cycle in
the waveform or gated region.
Negative Duty Cycle = ((Negative Width) / Period) × 100%
NEDGECount is the count of negative edges.
