Processing VITA signals

GNU Radio
1

I am a novice in the field of USRP & GNURadio.

I have a USRP NT210 with WBX. I need to process (read) timestamps of
received signal. I read that timestamps are included in the VITA format,
that I can select in GRC as a possible USRP output format. However I
wasn’t able to locate any other GRC block able to receive and process
VITA signals.

For example, can I store on file a received signal described by a VITA
signal?

Best regards

Hello Piero,
it might be helpful to look at " fpga/usrp2/vita/* "
for the vita code.

I will look at it during the weekend :slight_smile:

Hi Piero,
I’ve found something that could help you,
please refer to the following link:

and take a look at the section: “De/Serialization IO blocks”
it refers to VITA Radio Link Layer.
If I understood your request you might use the “deserialize block”.

Let me know if that helps,
ciao,

Fabio
