Visualize by ultimate isolation: The zone touch
trigger
One of the biggest challenges of using an oscilloscope is setting
up an advanced trigger to isolate a signal of interest. While
advanced triggers are powerful features, setting them up can
slow you down. The zone touch trigger provides a turnkey trigger
solution. You simply observe the signal of interest on the display
and draw a zone (box) around it with your finger. What used to
take hours of work can now take just a few seconds. If you want
to move your zones to another location, just drag them over. The
6000 X-Series can be set up to easily trigger on one or two zone
boxes simultaneously with either “must intersect” or “must not
intersect” conditions. Unlike other software-based graphical
trigger solutions, the hardware-based zone triggering maintains
the fast update rate of 160,000 waveforms per second. In other
words, if you can see it, you can trigger on it.
Visualize by protocol isolation: Serial protocol
trigger + the zone trigger
If isolating signal anomalies is challenging, isolating analog signal
phenomenon in relation to specific serial protocol packets is a
doubly difficult task. You can trigger on CAN bus errors if your
oscilloscope has a CAN serial bus trigger and decode option,
but how would you isolate a specific CAN error message from all
others?
Use the hardware-based zone trigger along with serial protocol
triggers. In Figures 13 and 14, we isolated a CAN steering bus
error message.
Figure 11. Draw a zone (box) around the anomaly.

packet trigger.

errors.
