Period
Measures the length of the left-most signal period within the displayed section of the
waveform. The measurement value is displayed as "T" in the result table.
Amplitude
Measures the amplitude of a square wave. To do so, the potential difference between
high and low level ("Vbase" and "Vtop") is calculated. The measurement requires at least
one complete period of a triggered signal. The measured value is displayed as "VAmp"
in the result table.
Crest factor
The crest factor is also known as peak-to-average ratio. It is calculated from the maximum
value divided by the RMS value of the waveform. The measurement value is displayed
as "Crest" in the result table.
Top Level
Measures the mean value of the high level of a square wave. To do so, the mean value
of the tilt is calculated (without the overshoot). The measurement and requires at least
one complete period of a triggered signal. The measured value is displayed as "Vtop" in
the result table.
Base Level
Measures the mean value of the low level of a square wave. To do so, the mean value
of the tilt is calculated (without the overshoot). The measurement requires at least one
complete period of a triggered signal. The measured value is displayed as "Vbase" in the
result table.
Pulse Width (positive pulse)
: Measures the width of a positive pulse. A positive pulse consists of a rising edge
followed by a falling edge. The measurement and requires at least one complete period
of a triggered signal. The measured value is displayed as "t " in the result table.
Pos. Overshoot
Positive overshoot of a square wave, calculated from measurement values Top Level,
Peak +, and Amplitude. The measured value is displayed as "+Ovr" in the result table.
Neg. Overshoot
Negative overshoot of a square wave, calculated from measurement values Min, Low,
and Amplitude. The measured value is displayed as "-Ovr" in the result table.
