Table 3-1 Sequence Execute Menu - Elgar SW 5550AE Operation Manual

Operation
SELECTION
Loads a sequence from the sequence library or the sequence scratchpad.
LOAD SEQ
When running under GPIB control, the Event Status Register and serial
polling can be used to indicate when the sequence loading is complete.
The front panel display will indicate "Processing sequence..." while
loading, and "Sequence loaded" when complete.
Configures the SYNC Trigger output to generate a pulse for every
SYNC
segment or only selected segments. When SYNC selection is changed,
you must reload the sequence.
Used to start a sequence, stop a sequence, or start a sequence in the
CONTROL
STEP mode. A sequence must be loaded before RUN or STEP can be
selected. All operations have an immediate effect.
RUN – Run the previously loaded sequence. A sequence does not need
to be reloaded when switching between RUN, STEP or STOP. The
sequence will begin executing immediately after a RUN or STEP
command.
STEP – Step through the previously loaded sequence. Each segment will
execute and remain at the value of the last cycle until instructed to
execute the next segment, or repeat the current segment. When stepping
through a sequence under front panel control, the F1 function key is used
to execute the next segment, and the F2 key is used to repeat the current
segment.
STOP – Stops the active sequence.
Specifies the running mode of the sequence. This parameter takes effect
RUN MODE
once a sequence has begun.
REPEAT – Repeats sequence until a STOP command is received.
SINGLE – Executes the sequence only once, then returns to the operation
specified in the STOP MODE field.
Specifies the mode of operation when a sequence is terminated. This can
STOP MODE
occur when running in the SINGLE execution mode, or when STOP is
selected.
ZERO – Programs the outputs to 0 volts when the sequence is terminated.
PROGRAM – The outputs are restored to the waveforms and values in
the Program Menu. This mode can be used for a continuous output
between sequences. The Program Menu cannot be modified while a
sequence is running. When this mode is selected, set BOOST to OFF
(see System menu).
END SEG – The outputs will remain at the waveforms and values of the
last segment in the sequence.
