Yes of course. There are buffers in the host and device (fifos).

Hi All,
I was wondering if there is any buffering happening on the host and/or on
the USRP (USRP1 and N210) when the UHD send() and recv() methods are called?
Thanks,
Shiva

Hi Josh,
Thanks for the reply.
Also, I want to know if this is correct: While we are working with signals
on the host PC, we're using complex float 64 bit data. This means we have 32
bit I data and 32 bit Q data. But when the USRP code (UHD or Gnuradio USRP
code) on the host PC sends this data

This is the buffer that the application fills with samples, and passes
into the call device->send()

Hello All,
I have a USRP1. I'm trying to run the tx_waveforms UHD example.
While using tx_waveforms, we have some parameters we nwwd to provide at the
command line.
1. What is the parameter --spb, samples per buffer. And generally, what is
this buffer?
2. What is the relationship between spb (s
