Automatic Time Marker Options - HP 16534A User Reference

Automatic Time Marker Options

When you touch the T Markers field a pop-up menu appears. When
you touch the Auto field in the pop-up, a pop-up menu for automatic
time marker measurements is displayed.
The automatic time marker measurements are made by setting the
time markers to levels that are either a percentage of the top-to-base
voltage value of a waveform or that specify voltage levels. The
top-to-base voltage value of a waveform is typically not the same as
the peak-to-peak voltage value. The oscilloscope determines the top
and base voltages by finding the flattest portions of the top and
bottom of the waveform. The top and base values do not typically
include preshoot or overshoot of the waveform. The peak-to-peak
voltage is the difference between the minimum and maximum voltages
found on the waveform.
If the signal is clipped, the time markers will not be automatically
placed.
When searching for the marker patterns, the search will occur only on
that part of the waveform that is displayed, not the entire stored
waveform.
The default Auto markers pop-up menu options are discussed in the
following paragraphs.
