• Sequence triggering— allows you to trigger the oscilloscope after
finding a sequence of events. Defining a sequence trigger requires three
steps:
a Define the event to find before you trigger on the next event. This
event can be a pattern, and edge from a single channel, or the
combination of a pattern and a channel edge.
b 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.
c 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.
• SPI (Serial Peripheral Interface) triggering— consists of connecting
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.
•TV triggering— is used to capture the complicated waveforms of
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.
• UART/RS- 232 triggering (with Option 232) — lets you trigger on
RS- 232 serial data.
• USB (Universal Serial Bus) triggering— will trigger on a Start of
Packet (SOP), End of Packet (EOP), Reset Complete, Enter Suspend, or
Exit Suspend signal on the differential USB data lines. USB Low Speed
and Full Speed are supported by this trigger.
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.
