The sweep flag is used to find out when logging data is available and when the next sweep cycle may be triggered.

It may also be used as a sweep cycle counter, where: flag/2 = number of sweep cycles The flag is:

-only used in continuous sweep

-set to 0 at start/end of sweep

-incremented when the sweep is waiting for a trigger

-incremented when logging data is available

-an odd number when, waiting for a trigger

-an even number when, logging data may be read

If the trigger input isn’t configured to start a sweep cycle the flag is increased by two when the logging data is available

If no logging data is calculated, because the user doesn’t want lambda logging, the flag is in- cremented at the end of the sweep cycle regardless
