how to use the GPSDO API.
- Is it possible to use X300 as NTP server? If so how could I achieve it?
No, it has no NTP support. GPS-based NTP servers are now quite cheap, so you
should probably look into one of those.

Santosh,
That card should be fine for streaming, that controller just hasn't been
explicitly tested as far as I know. Are you planning on using DPDK?

Hi There, Good morning. As I could see in the documentation, Ettus recommends
"X520 (Ethernet Controller)" at PC/host side. Is this a must? We are
planning to use X552 Ethernet Controller and I am wondering will it cause any
issue. Can you please let me know what are the Ethernet Controller

does work as well. I have runtime issues for which I have raised a different

Hi There, I have bench marked X300 against my development PC. Then I took
benchmark_rate code and modified a bit. Everything works fine except setting
the center freq. When ever I set the center frequency, there is no error

DPDK, I would recommend trying to use the DPDK transport,
but you will need to update to UHD 3.14.1.1 to support DPDK with the X310.
