Stream Portal | Time Machine

The Stream Portal block offers a local machine stream IO (similar to the HTTP block) but is much more efficient and includes an adjustable buffer for time critical missions:

Left hand side Input:

  •  Input (Stream)

Right hand side Output:

  •  Output (Stream)


In some cases the HTTP blocks offer not enough speed and a too high time delay e.g. if you want to stream the Rx IQ data directly to the Tx to build a signal loop. In this case you can use the Stream Portal blocks instead which is much more efficient since it does not struggle with the HTTP socket.

In addition you can adjust the buffer (via the stream delay time) by up to +/- 1s in fractions of 1 ns which makes it the worlds first real "Time Machine" :-).


The setup is quite simple:

A simple test mission using three SPECTRAN V6 units might look like attached:

ALPS has reacted to this post.

could you please change this mission and use stream portal instead of Http server and client ?

because your example mission was complicated and its difficult to understand Portal configuration well


Simply replace the HTTP with the Stream Portal:

Rx to Rx IQ stream


And what about Portal setting ?

here you used some setting for portal that I cant understand the meaning .


now for your sample example that you send a photo is it need any special setting or default setting is ok ?

could you please send a mission file ?
