Arguments
AMPlitude measures the amplitude of the selected waveform. In other words, it
measures the high value less the low value measured over the entire waveform or
gated region. This measurement is applicable only to the analog channels.
Amplitude = High - Low
AREa measures the voltage over time. The area is over the entire waveform or
gated region and is measured in volt-seconds. The area measured above the
ground is positive, while the area below ground is negative. This measurement is
applicable only to the analog channels.
BURst measures the duration of a burst. The measurement is made over the entire
waveform or gated r egion.
CARea (cycle area) measures the voltage over time. In other words, it measures, in
volt-seconds, the area over the rst cycle in the waveform or the rst cycle in the
gated region. The area m easured above the common reference point is positive,
while the area below the common reference point is negative. This measurement
is applicable only to the analog channels.
CMEan (cycle mean) measures the arithmetic mean over the rst cycle in the
waveform or the rst cycle in the gated region. This measurement is applicable
only to the analog channels.
CRMs (cycle rms) measures the true Root Mean Square voltage over the rst
cycle in the waveform or the rst cycle in the gated region. This measurement is
applicable only to the analog channels.
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 rst 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 applic able only
to the analog channels.
FREQuency measures the rst cycle in the waveform or gated region. Frequency
is the reciprocal of the period and ismeasuredinhertz(Hz),where1Hz=1
cycle per second.
HIGH measures the High reference (100% level, sometimes called Topline) of a
waveform. This measurement is applicable only to the analog channels.
LOW measures the Low reference (0% level, sometimes called Baseline) of a
waveform. This measurement is applicable only to the analog channels.
