Reporting the Setup
Use :TRIGger? to query setup information for the TRIGger subsystem.
Return Format
The return format for the TRIGger? query varies depending on the current
mode. The following is a sample response from the :TRIGger? query. In
this case, the query was issued following a *RST command.

finding a sequence of events. Defining a sequence trigger requires three
steps:
Define the event to find before you trigger on the next event. This
a
event can be a pattern, and edge from a single channel, or the
combination of a pattern and a channel edge.
Define the trigger event. This event can be a pattern, and edge from

a single channel, the combination of a pattern and a channel edge,
or the nth occurrence of an edge from a single channel.
Set an optional reset event. This event can be a pattern, an edge

from a single channel, the combination of a pattern and a channel
edge, or a timeout value.
the oscilloscope to a clock, data, and framing signal. You can then
trigger on a data pattern during a specific framing period. The serial
data string can be specified to be from 4 to 32 bits long.
television equipment. The trigger circuitry detects the vertical and
horizontal interval of the waveform and produces triggers based on the
TV trigger settings you selected. TV triggering requires greater than º
division of sync amplitude with any analog channel as the trigger
source.
