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.

; Param 1 (''R'')
; Block ID
: Description of parameter, provide any tips or recommended values. Note that the name of the parameter above should match the param's label that shows up in grc (e.g. Sample Rate).
: ID of another block in this flow graph. An empty Block ID references the flow graph itself.

; Function Name

: Name of a class method of the block labeled in Block ID.

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.

Periodically probe a function and set its value to this variable. To poll a stream for a level, use this with the Probe Signal block.

Parameters

(R): Run-time adjustable

Block ID
ID of another block in this flow graph. An empty Block ID references the flow graph itself.
Function Name
Name of a class method of the block labeled in Block ID.
Function Args
Parameters passed into the function specified under Function Name. For a function with no arguments, leave function args blank. When passing a string for the function arguments, quote the string literal: '"arg"'
The values will used literally, and generated into the following form:
   self.block_id.function_name(function_args)
or, if the Block ID is empty,
   self.function_name(function_args)
Poll Rate
in Hz.
Initial Value (R)
Initial value of function

Example Flowgraph
