CMEan (cycle me
an) measures the a rithmetic mean over the first cycle in the
waveform or the first cycle in the gated region. This measurement is available
onlyonDPOandMSOmodels.
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
availableonlyonDPOandMSOmodels.
DELay measures the time between the middle reference (default = 50%) amplitude
point of the source waveform and the destination waveform.
FALL measures 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 p
er second.
HIGH measures the High reference (100% level, sometimes called Topline) of a
wavef
orm. This measurement is available only on DPO models.
LOW measures the Low reference (0% level, sometimes called Baseline) of a
wavef
orm. This measurement is available only on DPO models.
MAXimum finds the maximum amplitude. This value is the most positive peak
volt
age found. It is measured over the entire waveform or gated region. This
measurement is available only on DPO models.
MEA
N
amplitude measurement finds the arithmetic mean over the entire waveform
or gated region. This measurement is available only on DPO models.
MI
NImum
finds the minimum amplitude. T his 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 c ount of falling edges.
NOVershoot (negative overshoot) finds the negative overshoot value over the
entire waveform or gated region. This measurement is available only on DPO
models.
Negative Overshoot = ((Low – Minimum) / Amplitude) × 100%)
NPULSECount is the count of negative pulses.
