27 :TRIGger Commands
• Pulse width triggering— (:TRIGger:GLITch commands) sets the oscilloscope to
trigger on a positive pulse or on a negative pulse of a specified width.
• Pattern triggering— identifies a trigger condition by looking for a specified
pattern. This pattern is a logical AND combination of the channels. You can also
trigger on a specified time duration of a pattern.
• 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 ¼ division of sync amplitude with
any analog channel as the trigger source.
