Identifying Items in the
Display
The following i
tems may appear in the display; not all items are visible at any
given time. Some readouts move outside the graticule area when menus are
turned off.
1. Waveform baseline icons show the zero-volt level of the waveforms (ignoring
the effect of offset). The icon colors correspond to the waveform colors.
2. Acquisition readout shows when acquisition is running, stopped, or when
acquisition preview is in effect.
3. Trigger position icon shows the trigger locati
on in the waveforms.
4. Expansion point icon shows the point that the horizontal scale expands and
compresses around.
5. Waveform record icon shows the trigger location relative to the waveform
record. The line color corresponds to the selected waveform color.
6. Trigger status readout show trigger status.
7. Trigger level icon shows the trigger level on the waveform. The icon color
corresponds to the trigger source channel color.
8. Cursor and measurement readouts show results and messages.
NOTE. Waveforms that extend beyond the screen (overrange) will display a
message in the measurement readout ("clipping"). This indicates that the
numerical readout is an invalid value. Adjust the vertical scaling to ensure the
readout is valid.
9. Trigger readouts show the trigger sources, slopes, and levels, and position.
