Strip Chart Tool
Overview
The Strip Chart tool plots histogram statistics at regular intervals defined by the user. The user can select
to view the AVERAGE of the measurements and/or the AVERAGE, plus the RMS Jitter or the ± peak jitter.
This is selected in the View pull-down menu. The most vertical data represents the highest one-shot
measurement of jitter and the lowest line being the most negative one-shot measurement of jitter. The
line in the middle is the measurement AVERAGE of all the data taken by the instrument.
The "Elapsed Seconds" displayed on the horizontal scale indicates the time over which the burst results
are graphically being displayed. In all, the data for up to 500 bursts are displayed across the screen.
The Elapsed Time for those 500 bursts depends on the time entered into "Interval(s)", which is on the
Dialog Bar. When the user selects "Cycle" from the Tool Bar, the display will continuously move from
right to left with the "Elapsed Seconds" time stamping the burst data being displayed within the graph.
This allows long-term effects, such as environmental effects of long-term drift, to be measured. For
example, histograms of period measurements could be made at every interval, i.e. 10 minutes, and the
mean, 1-sigma, pk-pk, and max/min values plotted over a long time, i.e. overnight.
