Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.

Symbols
Set of symbols to correlate against (e.g., a sync word).
Samples per Symbol
Samples per symbol
Tag Marking Delay (R)
Tag marking delay in samples after the corr_start tag
Threshold (R)
Threshold of correlator: 1-(Probability of False Alarm). Default 0.9.
Threshold Method
options: [Absolute, Dynamic]
