Amplitude measurements (cont.)
Measurement Description
Positive
Overshoot
This is measured over the entire waveform or gated region and is expressed as:
Positive Overshoot = (Maximum – High) / Amplitude x 100%.
Negative
Overshoot
This is measured over the entire waveform or gated region and is expressed as:
Negative Overshoot = (Low – Minimum) / Amplitude x 100% .
Mean
The arithm
etic mean over the entire waveform or gated region.
Cycle Mean The arithm
etic mean over the firstcycleinthewaveformorthefirst cycle in the gated
region.
RMS The true Root Mean Square voltage over the entire waveform or gated region.
Cycle RMS The true Root Mean Square voltage over the first cycle in the w aveform or the first
cycle in
the gated region.
Miscellaneous measurements
Measurement Description
Positive Pulse
Count
The number of positive pulses that rise above the mid reference crossing in the waveform
or gated region.
Negative Pulse
Count
The number of negative pulses that fall below the mid reference crossing in the waveform
or gated region.
Rising Edge
Count
The number of positive transitions from the low reference value to the high reference
value in the waveform or gated region.
Falling Edge
Count
The number of negative transitions from the high reference value to the low reference
value in the waveform or gated region.
