Message Strobe

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

(R): Run-time adjustable

Message PMT (R)

The message to send as a PMT.

Period (ms) (R)

The specified time interval after which data is sent at the output repeatedly.

Example Flowgraph

Example 1

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

Example 2

In another example, we change the frequency of a signal source to 1kHz after 5 seconds.

The message strobe settings in the above example are as follows:

Example 3

Another example that uses a Message Strobe block can be found in gr-blocks/examples/msg_passing/strobe.grc.
