7.21 Regional Trigger
For complicated and volatile circuit signal in circuit debugging, the oscilloscope with high waveform
capture rate can easily observe fleeting accidental abnormal signal. If user want to separate the
abnormal signal from complicated and volatile circuit and to stable triggered. It may take a lot of time to
learn the using of some advanced trigger and even so some more powerful advanced trigger also cannot
full triggered.
MSO/UPS2000 series add the screen touch regional trigger function, it's really helpful for user to get the
using of advanced trigger. Regional trigger function is very easy to use. User just need to open rectangle
drawing function to draw one or two rectangle areas in the corresponding signal, it can quickly separate
it and for observing signal. Regional trigger can combine with basic trigger, advanced trigger and
protocol trigger function and it also supports decoding, recording waveform and pass/fail test. It's really
convenient for debugging complicated signal.
Regional trigger provides tow rectangle areas: Region A and Region B. Both regions support setting the
region trigger condition to intersection or non-intersection; and the two regions support setting the
corresponding enable sources CH1, CH2, CH3, CH4.
(1) Rectangle drawing menu can set region A enable, source A, region B enable, source B.
a. Region A enable: Set whether Region A is effective, it can be ON or OFF.
If there is a region frame is display on the screen, ON: display region frame; OFF: turn off region
frame.
b. Source A: Set source of region A enable, which can be CH1~CH4.
c. Region B enable: Set whether Region B is effective, it can be ON or OFF.
If there is a region frame is display on the screen, ON: display region frame; OFF: turn off region
frame.
d. Source B: Set source of region B enable, which can be CH1~CH4.
(2) Rectangle drawing menu can set cancel, 1: intersection, 1: non-intersection, 2: intersection, 2: non-
intersection.
a. Cancel: Turn off the current drawn region and cancel the condition.
b. A: intersection: The current drawn region is Region A trigger.
Condition: It will be triggered if region A intersects with source A waveform, if it not triggered then
not intersected.
c. A: non-intersection: The current drawn region is Region A trigger.
Condition: It will be triggered if region A is not intersect with source A waveform, if it intersected
then not triggered.
d. B: intersection: The current drawn region is Region B trigger.
Condition: It will be triggered if region B intersects with source B waveform, if it not triggered then
not intersected.
e. B: non-intersection: The current drawn region is Region B trigger.
