DELay measures the time between the middle reference (default = 50%) amplitude
point of the source waveform and the destination waveform. This measurement is
applicable only to the analog channels.
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 m easurement is applicable only
to the analog channels.
FREQuency measures the rst 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 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.
MAXimum nds 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 applicable only to the analog channels.
MEAN amplitude measurement nds the arithmetic mean over the entire waveform
or gated region. This measurement is applicable only to the analog channels.
MINImum nds 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 applicable only to the analog channels.
NDUty (negative duty cycle) is the ratio of the negative pulse width to the signal
period, expressed as a percentage. The duty cycle is measured on the rst cycle in
the waveform or gated region.
Negative Duty Cycle = ((Negative Width) / Period) ×100%
NEDGECount is the count of negative edges.
NOVershoot (negative overshoot) nds the negative overshoot value over the
entire waveform or gated region. This measurement is applicable only to the
analog channels.
Negative Overshoot = ((Low - Minimum) / Amplitude) × 100%)
NPULSECount is the count of negative pulses.
NWIdth (negative width) measurement is the distance (time) between the middle
reference (default = 50%) amplitude points of a negative pulse. The measurement
is made on the rst pulse in the waveform or gated region.
PDUty (positive duty cycle) is the ratio of the positive pulse width to the signal
period, expressed as a percentage. It is measured on the rst cycle in the
waveform or gated region.
Positive Duty Cycle = ((Positive Width)/Period) × 100%
