Math and Measure
For any parameter that computes on every event, the num statistic represents the number of events
per acquired waveform. If
x
waveforms were acquired, num is
x
times the number of cycles per
waveform.
To reset the statistics counter, touch
Clear Sweeps
on the display or front panel.
Histicons
Histicons are miniature histograms of measurement parameters that appear on the measurement
table. These thumbnail histograms let you see at a glance the statistical distribution of each
parameter. Select the
Histicons
checkbox to turn on histicons.
Tip:
You can quickly display a full histogram by touching the histicon you want to enlarge.
Help Markers
Help Markers clarify measurements by displaying lines, labels and hysteresis bands to mark the
points being measured on the trace. For "@Level" parameters, markers make it easier to see where
your waveform intersects the chosen level.
You can choose to use
Simple
markers, which are only the lines, or
Detailed
markers, which include
the measurement point labels.
You also have the option, by means of the
Always On
checkbox, to leave the markers displayed over
traces after you have closed the Measure dialogs or readout table. If you change the set of
parameters displayed, the markers will change, as well.
Note:
Unlike regular cursors, which are white and can be moved, help markers are blue and
only augment the display; they cannot be moved, and they do not reset the measurement
points. Some optional analysis software packages include markers designed specially for
that domain of reference, which are documented in the option manual.
Detailed Help Markers on standard horizontal parameters.
