oscimpDigital support for AntSDR E200?

[aewallin]

Hi oscimpDigital gurus!

We would like to build fiber-noise-cancellation servos using oscimpDigital, and the AntSDR E200 looks interesting because it can take a 10MHz reference frequency input (easier to find in the lab, compared to a 125 MHz clock for RedPitaya), and the RF-frontend (AD9361) supports RF compatible with typical AOMs (e.g. 80-200 MHz) used for fiber-noise-cancellations (with RedPitaya we would need to up-convert TX for driving the AOM, and down-convert for the 2*AOM beatnote RX).
There is info about the AntSDR E200 e.g. here: https://antsdr-docs.microphase.cn/en/latest/device_and_usage_manual/ANTSDR_E_Series_Module/ANTSDR_E200_Reference_Manual/AntsdrE200_Reference_Manual.html
availability seems OK, from e.g. mouser.

thanks for any comments!

Another hardware platform that looks similar (but the price is higher) is Signalens SignalSDR Pro (AD9361 RF-frontend and Zynq 7020)

Thank you for these excellent pointers which open new perspectives for SDR applications. For noise cancellation/metrological applications, I would be careful with the fancy, powerful but hardly understandable AD9361. My tests on time transfer using this frontend did exhibit some degradation with respect to a direct ADC, even when using upper Nyquist zones. See Fig 11 of https://pubs.gnuradio.org/index.php/grcon/article/view/142/120
Nevertheless, integrating the AD9361 frontend in OscimpDigital would be very interesting, if only with respect to this other board you forgot to mention https://enjoy-digital-shop.myshopify.com/products/litex-m2-sdr-si5351b
Thanks.
