Hi Martin,
Sorry I called you Marcus earlier, I was probably thinking of Marcus of
GNURadio. Two things:
1. Is it safe to assume that packets on the data plane are not buffered.
Like if there are 64 samples in the packet, that those 64 samples are the
most current 64 samples. For instance, if t
The answer is yes.

Hello all,
I am using USRP x300 device. I want to receive data continuously store it on
ddr memory and transmit it after variable time delay. I know there will be
constraint on the maximum time (because of ddr size) I can wait before starting
transmission and I am ok with it. But after a fixed
Hey Mark,
that all makes sense, but keep in mind that the DDC comes later in the
data path than the radio samples, which means the timestamps are "in the
past" with respect to the actual GPIO events. In theory, we don't even
guarantee deterministic latency (they could vary by how much in the past
Hi Marcus,
Thank you. You've been very helpful and confirmed my thoughts.
Yes it will be important to run the sampling of the GPIO pin at the same
rate produced by the DDC. I didn't fully appreciate that the data was
packetized which makes this more difficult than I'd thought.
