Sequencer Configuration

7.7.3.1

General Information

When configuring the sequencer, the following rules apply:
Required parameter values
Sequencer Set Start values must always be set to 0. This ensures that sequencer set 0 is

always the first set available for image acquisition after sequencer start or reset.
The Sequencer Trigger Activation parameter must always be set to Level High (positive logic).

The other path-related parameter values must differ between paths 0 and 1, in particular the

Sequencer Trigger Source parameter value. We recommend to first set the path-specific
sequencer trigger sources for sequencer set 0 and then the path-specific sequencer trigger
sources for the other sequencer sets.
Each sequencer set must include exactly one subset of parameter values relating to path 0

and exactly one subset relating to path 1.
This ensures that each sequencer set "knows" what role to play within each path, i.e. within
each sequencer set advance scheme.
Additional rules for configuring sequencer set 0
For Sequencer Set 0, the Sequencer Set Next value must be set to path 0. In addition, the

Sequencer Set Next value must be set to Sequencer Set 1 for path 1 in order to be able to
"leave" user set 0 during image acquisition and to realize the application described in
Section 7.7.4 on page
Additional rules for configuring sequencer sets for path 1
The sequencer sets must be configured in order of ascending and consecutive index numbers.

For all sequencer sets except for the one with the highest index number: The Sequencer Set

Next parameter value set for sequencer set J must always be set to sequencer set index
number (J+1). For example, for path 1 used with sequencer set 2 the Sequencer Set Next
parameter value must be set to 3.
For the sequencer set with the highest index number: The Sequencer Set Next parameter

value for path 1 used with the sequencer set with the highest index number must be set to 0.
For example, if four sequencer sets are to be used, the Sequencer Set Next parameter value
for path 1 used with the fourth sequencer set (index number = 3) must be set to 0.
This ensures that each sequencer set cycle (according to path 1) resumes with sequencer set 0.
