Max throughput with pluto devices as standalone device

Hello,

the usb give us a max trougthput between 24-21MB between the host and the pluto device for this reason we have a limit capture sampling rate.

but what happens if we capture signal directly in pluto device with the embedded linux?. what max throughput we can achieve?.

how we can test it?.

Thanks,

regards,

j.

    If you what to add additional tools you need to rebuild your firmware.

    Alternatively copy the files over to your pluto using SCP, or share files using the USB thumb drive.
