Name Definition
Period Timing measurement. Time it takes for the first complete signal cycle to happen
in the waveform or gated region. The reciprocal of frequency. Measured in
seconds.
Positive Duty
Cycle
Timing measurement of the first cycle in the waveform or gated region. The
ratio of the positive pulse width to the signal period expressed as a percentage.

Positive Width Timing measurement of the first pulse in the waveform or gated region. The
distance (time) between MidRef (default 50%) amplitude points of a positive
pulse.
Rise time Timing measurement. Time taken for the leading edge of the first pulse in the
waveform or gated region to rise from a Low Ref value (default = 10%) to a
High Ref value (default = 90%) of its final value.
RMS Voltage measurement. The true Root Mean Square voltage over the entire
waveform or gated region.
