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 arithmetic mean over the entire waveform or gated region.
Cycle Mean The arithmetic mean over the fi rst cycle in the waveform or the fi rst 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 fi rst cycle in the waveform or the fi rst
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.
