Support for Trigger-Data without related WR-Event
There is an Unilac Digitizer-System which needs to trigger on a raising signal edge, not on WR-Events.
- gr-digitizers already supports triggering e.g. on a raising edge instead of a wr-event. (Mode: DIJUNCT_MULTI_SAMPLE)
- Current procedure is, that the Digitizer FESA class received as tag from gnuradio which contains a stamp to find a corresponding WR event.
- In the future, that "finding a WR-Stamp" should be optional, so the metadata passed to cabad cannot have a
TimingContext
. We will have a Timestamp-Only MetaData item only.- The Digitizer adds a trigger-tag with UTC-timestamp to the trigger-data. (See related code here)
- If required, it would be fine to enable that mode via some flag on the ctor of the buffer-.manager. Though ideally it should work without.
- To be tested with the Digitizer FESA class (disable adding data to the context tracker for testing)
