The oscilloscope turns vectors on whenever the acquisition system stops. Digital
channels on the mixed-signal oscilloscope are not affected by the Display Menu. They are
always displayed with vectors on. They also only contain one trigger worth of information.
Using Vectors (Display Menu)
One of the most fundamental choices you must make about your display is whether to
draw vectors (connect the dots) between the samples, or simply let the samples fill in the
waveform. To some degree, this is a matter of personal preference, but it also depends on
the waveform.
• You will probably operate the oscilloscope most often with vectors on. Complex analog
signals like video and modulated signals show analog-like intensity information with
vectors on.
• Turn vectors off when highly complex or multivalued waveforms are displayed. Turning
vectors off may aid the display of multivalued waveforms such as eye diagrams.
• Having vectors on does not slow down the display rate.
To freeze the display without stopping running acquisitions:
1 Press the [Display] key.
2 Press the Freeze Display softkey.
To un-freeze the display, press Freeze Display again.
Many activities, such as adjusting the trigger level, adjusting vertical or horizontal
settings, or saving data will un-freeze the display.
Manual cursors can be used on the frozen display.
