MAXImum finds the maximum amplitude. This value is the most positive peak
voltage found. It is measured over the entire waveform or gated region.
MEAN is the arithmetic mean over the entire waveform or gated region.
MINImum finds the minimum amplitude. This value is typically the most
negative peak voltage. It is measured over the entire waveform or gated region.
NDUty is the ratio of the negative pulse width to the signal period expressed 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 number of negative transitions from the high reference value
to the low reference value in the waveform or gated region.
NOVERshoot is measured over the entire waveform or gated region and is
expressed as:
Negative Overshoot = (Low – Minimum) / Amplitude * 100%.
NPULSECount is the number of negative pulses that fall below the mid reference
crossing in the waveform or gated region.
NWIdth (negative width) measurement is the distance (time) between the middle
reference (default = 50%) amplitude points of a negative pulse.
PDUty (positive duty cycle) is the ratio of the 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 number of positive transitions from the low reference value
to the high reference value in the waveform or gated region.
PERIod is the duration, in seconds, of the first complete cycle in the waveform or
gated 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 gated region.
POVERshoot is the positive overshoot value over the entire waveform or gated
region. The measurement is expressed as:
Positive Overshoot = (Maximum – High) / Amplitude * 100%.
PPULSECount is the number of positive pulses that rise above the mid reference
crossing in the waveform or gated region.
PWIdth (positive width) is the distance (time) between the first rising edge and
the next falling edge at the waveform 50% level (default). Rising and falling
edges must be displayed to measure. The measurement is made on the first pulse
in the waveform or gated region. The instrument automatically calculates the
50% measurement point.
