Source
Select the source for you parameter measurement. The source for a measurement made on a decoded
waveform should be the DecodeX applied to the channel and not the Cx channel itself.
Measure
Click in this field to select the desired measurement from the pop-up.
Protocol measurements (where applicable) can also be selected as the source for histogram, trend, or track
functions.
Actions for Px

Histo - The Histogram displays a statistical distribution of a measurement parameter. Histogram is helpful
to understand the modality of a measurement parameter, and to debug the root cause of excessive
variation.
Note: After touching Histo, Trend, or Track buttons, a Math selection pop-up is shown to select which
Math trace in which you want the results to be placed.

Trend - The Trend statistical tool visualizes the evolution of a timing parameter over time in the form of a
line graph. The graph’s vertical axis is the value of the parameter; its horizontal axis is the order in which
values were acquired. Trend is typically used for a multi-shot acquisition. Trend is analogous to a chart
recorder.

Track - The Track displays a time-correlated accumulation of values for a single acquisition. Track can be
used to plot the digital-to-analog converted (DAC) values of serial data (using the Message to Value
parameter) and compare them to a corresponding analog signal, or observe changes in timing. Track is
typically used for a single-shot acquisition. A long acquisition with many parameter measurements
analyzed with Track could provide information about the modulation of the parameter.
