Period
"Period" measures the duration of the signal period T. The period identifies the dura-
tion between two equal values of one periodically repeated signal.
Amplitude
Measures the amplitude of a square wave signal (V
Amp
). The measurement calculates
the difference in voltage between the upper and the lower level (V
base
and V
top
). The
measurement requires at least one complete period of a triggered signal.
Crest Factor
The crest factor (peak-to-average ratio) is calculated from the maximum value divided
by the RMS value of the waveform (Crest).
Top Level
"Top Level" measures the mean voltage level of an upper square wave (V
Top
). The
measurement calculates the mean value of the roof slope without overshoot. The mea-
surement requires at least one complete period of a triggered signal.
Base Level
"Base Level" measures the mean voltage level of the lower square wave (V
Base
). The
measurement calculates the mean value of the roof slope (without overshoot). The
measurement requires at least one complete period of a triggered signal.
Pos. Overshoot
"Pos. Overshoot" measures the positive overshoot of a square wave which is calcula-
ted from top level, peak + and amplitude value (+Ovr).
Neg. Overshoot
"Neg. Overshoot" measures the negative overshoot of a square wave which is calcula-
ted from base level, peak - and amplitude value (-Ovr).
Pulse Width +
"Pulse Width +" measures the width of the positive pulse. A positive pulse consists of a
rising slope followed by a falling slope. The measurement identifies the two slopes and
calculates the pulse width from their time difference. The measurement requires at
least one complete period of a triggered signal.
