IQ data collection
I am a noob. Now I am using an SDR receiver, how to get the IQ data after digital down-conversion? I don't want to use SDR software.

Re: IQ data collection
You can find two Python scripts that can be used to record and playback the IQ data at this link. They work with the wideband SDR transceiver.

Re: IQ data collection
Thank you very much for your reply. My model is 125-14, is this py script available? In addition, are these two files flashed to the SD card? As a rookie, I don't know the specific operation steps. My current PC is a Windows system. Do I need to change it to Linux?

Re: IQ data collection
Can you tell me steps on how to get IQ data and continuous acuqisitions uising my redpitaya?
the model I have is also same as you-2 inputs and 2 outpus stemlab-14

Re: IQ data collection
Looks very straightforward Pavel. Perfect. Are frequencies above 2.5M sampling too high to store to MMC? Or is it Python not keeping up?

Re: IQ data collection
I am afraid I do not understand the question and how MMC is involved.
The Python scripts in my comment need to be run on a computer and communicate with the Red Pitaya board via the Ethernet interface.
Here is a link to a forum thread with more details on the project these scripts were developed for:
viewtopic.php?f=7&t=1030&start=10#p32553
For higher sample rates I have a couple of wideband receiver projects:
https://github.com/pavel-demin/red-pita ... eiver_wide
https://github.com/pavel-demin/red-pita ... ide_122_88
They are both dual channel receivers. The sample rates are 3.9 MSPS and 10.24 MSPS. The samples are 16-bit IQ samples.
