Phase
This timing measurement is the amount of time that one waveform leads or lags another
waveform. The measurement is expressed in degrees where 360° comprise one waveform cycle.
Phase Argument
Inserts the text SpectralPhase( ) into the math expression. Select one of the waveforms as an
argument to the function. This function creates an FFT phase waveform.
Pk-Pk
Displays the peak-to-peak value of the histogram. Vertical histograms display the "voltage" of the
highest nonzero bin minus the "voltage" of the lowest nonzero bin. Horizontal histograms display
the "time" of the rightmost nonzero bin minus the "time" of the leftmost nonzero bin.

Positive Duty Cycle
This timing measurement is the ratio of the positive pulse width to the signal period expressed as a
percentage. The duty cycle is measured on the first cycle in the waveform or gated region.
Positive Duty Cycle = (Positive Width) ÷ Period × 100%
Positive Overshoot
This voltage measurement is measured over the entire waveform or gated region and is expressed
as: Positive Overshoot = (Maximum – High) X Amplitude X 100%.
Positive Width
This timing measurement is the distance (time) between the mid reference (default 50%)
amplitude points of a positive pulse. The measurement is made on the first pulse in the waveform
or gated region.
