3 Sequencing
92 M8190A User’s Guide
A sequence can be played standalone (see Sequence Mode) or can be part of a
scenario.
Multiple sequences can be combined into a scenario (see Scenario Mode). A scenario
can be executed continuously or a specified number of times.
The trigger mode defines the way, how segments, sequences and scenarios begin with
playing waveform data. After having setup the instrument, it is started. Then the start of
segments, sequences and scenarios depends on the different trigger modes.
In the trigger mode Continuous, the sequencer is started immediately after the
instrument. In this mode, the waveform execution is infinite.
In the trigger mode Triggered, the sequencer needs a trigger to start. After having
received the trigger, the waveform is played a defined number of times, and then the
sequencer is stopped again and is prepared to accept the next trigger. Every trigger
that occurs before the currently running segment/sequence/scenario has completed, is
ignored. Alternatively, after having received a trigger, a waveform can also be played
infinitely. See Sequencer Modes for more details.
