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.

Send message at defined interval.

Takes a PMT message and sends it out every milliseconds. Useful for testing/debugging the message system.

The PMT to send seems to be settable also from the input port (please confirm that)

Parameters[edit]

(R): Run-time adjustable

Message PMT (R)
The message to send as a PMT.
Period (ms) (R)
The time period in milliseconds in which to send

Example Flowgraph[edit]

In this example, a Message Strobe block sends the string "Demo" once per second.
