Hi Seckin,

it's unlikely your processor is the problem here – if anything, it's the 40·10⁶·64b/s ~= 2.4 Gigabit per second that you're reading from your storage from two different files. Storage devices and file systems have pretty non-deterministic and large-variance read speeds and access times, and this might be a problem here.

Does this also fail if you just connect two "null sources" instead of "file 
sources"?

Best regards,
Marcus

Hello,

I am trying to use both channels of N320 to transmit the recorded files. But after a certain times it gives “U” error and stop transmits at that channel. (The led light of ch0 or ch1 turns off). Then it gives again “U” error and the other led turns off. Then “L” error occurs. The problem happens over 20 MSPS of sample rate. Related figures are attached.

Why N320 stops transmitting when “U” error occurs? Isn’t it strange?

There is no problem when transmitting on one channel.

I have intel x520-da2 NIC, i7 8700 processor. I think it shouldn’t be a problem to transmit at 20 Msps sample rate.

Thanks

Seckin
