TIMING PARAMETERS
Timing parameters can also be used to measure cycle-to-cycle jitter, the width of positive and
negative pulses, the duty cycle of either polarity, and an infinite number of cycles on long records.
Pulses or cycles can be counted using one of these parameters.
As interpolation filtering is applied to signal edges in the vicinity of measurement points, timing
parameters operate on acquired waveform levels that may be selected in either volts or
percentage of signal amplitude. Each parameter calculation is performed over all cycles or edges
present in the input signal, without limitations.
Statistical Tools
The information obtained from applying timing parameters can then be analyzed using the
statistical tools, histograms and trends:
• Histograms characterize and present as a bar chart the statistical distribution of a timing
parameter’s set of values. In addition, there are 18 statistical histogram parameters,
which operate directly on the histogram.
• Trends represent the evolution of timing parameters in line graphs whose vertical axes
are the value of the parameter, and horizontal axes the order in which the values were
acquired.
