V6 direct I/Q stream

#1 · 06/11/2020, 18:36

Hello,

I have read that V6 has the possibility to stream I/Q data through the USB 3.0 port.

Will there be the possibility to record I/Q data without first storing spectrum data?
Will it maybe a possibility given by the V6 block?

(I'm sorry the block is not included in the demo so I cannot know if it will have an I/Q output)

Hi Lorenzo,

The Spectran V6 provides IQ data directly. It also provides spectrum data, by calculating internally the FFT of the IQ data (see attachment). Also have a look at the function diagram of the Spectran V6 https://v6-forum.aaronia.de/forum/topic/spectran-v6-function-diagram-x-and-oem-version/

Thank you, now that I see the Block i understand reception of IQ data. What about the opposite operation? Having IQ data stored in the computer and wanting to send them through the air using the V6: is it possible? Maybe using the "File Reader" block?

Yes no problem if you have a Tx license.

In that case you can stream I/Q data to the V6 (up to 120MHz) with the help of the IQ Signal Generator block or the File Reader.

The simplest missions would look like the attached.

Please note that the IQ Signal Generator block already offers a lot of signal standards e.g. AM, FM, Pulse, Sweep, PPSK, QAM etc.

BTW: You can stream to the Tx and receive from any Rx at the same time.

Thanks! So a RF record and playback operation would look like the one below.

You said Tx license. So I would need:

V6
Tx License
RTSA

Anything else?

Your docking setup is not quite correct (see attached layout) since you can't add a transmitter antenna to the Spectran V6 block but yes that's all you need.

A SPECTRAN V6 RSA-500X or RSA-2000X includes it all:

Dear Sir,
I try to stream data to the Tx of the Spectrum and see it at the Spectran Rx.
Pease find block diagram.
My RSTA SW version is
Product: Aaronia RTSA-Suite PRO
Version: 1.5.152.9160
BuildDate: 2021.7.19

Please guide me how to proceed.
Seeblock diagram picture.
I don't know wy The Spectran V6 module has USB overflow.

Please send more details.

Your screenshot misses all setups and there is no mission file attached.

Which V6 do you have and which license?

#9 · 21/07/2021, 12:50

Thank for the update.
Add setup file and full picture of Spectran RSTA screen.
I use my customer new Spectran V6-RSA500X sn A3-x-02000033.
Note: It write Rx and Tx underflow.

Seems your hard drive or CPU is to slow to stream the data since you have a huge amount of errors on your USB link.

Also check the cabling.

Attache mission files as ZIP only otherwise we cant download those.

BTW: For sure your recording is NO IQ file which is causing the problems since you can't stream non IQ to the SPECTRAN.
