MAXimum finds th
e 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 finds the arithmetic mean over the entire waveform
or gated region. This measurement is applicable only to the analog channels.
MINImum finds the minimum amplitude. This value is typically the most negative
peak voltage. It is measured over the entire waveform o r 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, express ed as a percentage. The duty cycle i s measured on the first cycle in
the waveform or gated region.
Negative Duty Cycle = ((Negative Width) / Period) × 100%
NEDGECount is the count of falling edges.
NOVershoot (negative overshoot) finds 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 first 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 first cycle in the
waveform or gated region.
Positive Duty Cycle = ((Positive Width)/Period) × 100%
PEDGECount is the count of rising edges.
PERIod is the time required to complete the first cycle in a waveform or gate d
region. Period is the reciprocal of frequency and is measured in seconds.
PHAse measures the phase difference (amount of time a waveform leads or lags
the reference waveform) between two waveforms. The measurement is made
between the middle reference points of the two waveforms and is expressed in
degrees, where 360° represents one waveform cycle.
PK2Pk (peak-to-peak) finds the absolute difference between the maximum and
minimum amplitude in the entire waveform or g ated region. This measurement is
applicable only to the analog channels.
POVershoot is the positive overshoot value over the entire waveform or gated
region. This measurement is applicable only to the analog channels.
Positive Overshoot = ((Maximum - High) / Amplitude) ×100%
