Zone Trigger
MSO8000 series oscilloscope supports the zone trigger and provides two rectangle

"Intersect" or "Not intersect". Refer to "Rectangle Drawing" to select "Trigger
zone A" or "Trigger zone B" to open the zone trigger setting menu. You can also press
Measure → Analyze → Zone trigger to enter the zone trigger setting menu.
Enable or disable Trigger zone A or Trigger zone B:
Press Zone A enable or Zone B enable continuously to enable or disable Trigger
zone A or Trigger zone B. You can also refer to "Rectangle Drawing" to select
"Trigger zone A" or "Trigger zone B" to enable Trigger zone A or Trigger zone B. If
both Trigger zone A and Trigger zone B are disabled, then the zone trigger function is
disabled. At this time, you must enable either of them to re-enable the zone trigger.

If "XY Mode" or "ROLL Mode" is enabled, the zone trigger function is
disabled.

press Source A or Source B continuously to select the trigger source, or enable the
touch screen to tap the desired trigger source and select it. The available sources
include CH1-CH4. The zone name color and the zone color are the same as the color
of the selected source channel.
Set the conditions for Trigger zone A and Trigger zone B:
Press Zone A or Zone B, rotate the multifunction knob
to select "Intersect" or
"Not intersect", then press down the knob to select it. You can also press Zone A or
Zone B continuously to select the condition, or enable the touch screen to tap the
