Behavior
The instrument provides the following trigger type categories.
■
Edge triggers. This is the most commonly used trigger type. You can use Edge triggers with analog and digital signals.
Edge triggers are available on both the Main and Delayed triggers.
■
Pulse triggers. These are special-purpose triggers that are primarily used with digital signals. The following classes of
pulse triggers are available:
Glitch , Runt , Window , Width , Transition , and Timeout . Pulse triggers are only available on the
main trigger.
NOTE. Pulse trigger on B Events is not available on MSO/DPO5000B Series instruments.
■
Logic triggers. These are special-purpose triggers that are primarily used with digital logic signals. Two of the classes,
Pattern and State (State triggers are not available on DPO70000SX ATI instruments), trigger the instrument based on the
Boolean operator you select for the trigger sources. A third class, Setup and Hold , triggers when data on one trigger source
changes state within the setup and hold times that you specify relative to a clock on another trigger source. Logic triggers
are only available on the main trigger.
NOTE. Logic trigger on B Events is not available on MSO/DPO5000B Series instruments.
■
Window. Use the Window trigger to trigger the instrument when the input signal rises above an upper threshold or falls
below a lower threshold level.
NOTE. Window trigger on B Events is not available on MSO/DPO5000B Series instruments.
NOTE. Bus trigger on B Events is not available on MSO/DPO5000B Series instruments.
Bus. Use to trigger on parallel or serial bus signals.
NOTE. Some Bus triggers may not be available unless your instrument has a specific option installed.
■
CAN Bus. Use to trigger on CAN Bus signals.
■
SPI. Use to trigger on Serial Peripheral Interface signals.
■
I2C. Use to trigger on Inter-IC signals: start, stop, repeated start, missing acknowledge, address, data, and address and
data.
■
RS-232. Use to trigger on RS-232 signals.
■
Envelope. Use to trigger on the envelope of an AM carrier.
■
Period. Use to detect a period as two sequential crossings of same polarity.
■
Frequency. Use to trigger on a frequency.
■
Comm. The Communication triggers are designed to work with communication masks and standards.
NOTE. Comm trigger on B Events is not available on MSO/DPO5000B Series instruments. Comm triggers are not available
on DPO70000SX instruments.
■
Serial. Serial is a special trigger type used on signals with serial data patterns.
NOTE. Serial trigger on B Events is not available on MSO/DPO5000B Series instruments.
