Generates a default header for a tagged, streamed packet based on the specified length. This block is a special case of [[Packet Header Generator]]
This is the template for the [[:Category:Block_Docs|"Page-per-block Docs"]]. This first section should describe what the block does and how to use it, using however many paragraphs necessary.  Note that the title of the wiki page should match the block's name in GRC, i.e. the one defined in the block's .grc file.  Look at the [[FFT]] Block for a good example.


As this is a basic template, it's also in the [[:Category:Stub_Docs|"Stub Docs category"]]. Please improve it.
Input: A tagged stream of bytes. This is consumed entirely, it is not appended to the output stream. Note that all 8 bits per byte are used.
 
Output: An tagged stream containing the header.

Generates a default header for a tagged, streamed packet based on the specified length. This block is a special case of Packet Header Generator

Input: A tagged stream of bytes. This is consumed entirely, it is not appended to the output stream. Note that all 8 bits per byte are used.

Output: An tagged stream containing the header.

Parameters

Header Length
This is the number of bits per header.
Length Tag Name
Length tag key.

Example Flowgraph

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.
