Hi all,
I am trying to figure out what I am doing/thinking wrong in the
following example:
I have a simple flowgraph with a complex source sending samples to USRP.
The sample rate is fs=200e6/32=6.25 Msps which is the parameter that I
set in the USRP.
I assume that this parameter will result in fs x 8 = 50 MBytes/sec
transmission
over the ethernet (2 complex samples and float32 (4 bytes) each. This
is the format that I have set in USRP).
However, when I observe the transmission rate on the system monitor
(Ubuntu Linux) it reports a sustained rate of exactly half of it, ie,
25 MBytes/sec.
I cannot figure out what I am doing wrong and I get this factor of 2
mismatch.
All the above is run in an ubuntu box with gnuradio maint-3.7
installed and uhd 3.14.0
thanks in advance for any explanation,
Achilleas
