Hello everyone,
I just wanted to ask that if it is possible to use a single system
hooked up
to multiple USRP2’s (4 in my case) to act as both a transmitter and
receiver
using the USRP2 source and sink blocks in GRC. The source and sink
blocks
are working fine independently, but if I use them in the same flow graph
the
source block outputs garbage or something which I can’t really make
sense
of. I’ve checked using QAM modulation, FM and just sending plain
constellation points/symbols, but at the output of the source I’m
receiving
only noise.
Attaching the Screenshot of my test flow graph running showing an
instance
of what I am getting. In most examples and demonstrations I’ve seen
transmitter and receiver on different systems but as we have not set the
2nd
system up yet I can’t test using that, so I was wondering if it is
possible
somehow to use only 1 system as a transceiver. I am using separate
USRP2’s
as shown in the screenshot for transmit and receive, eth1 and eth4 in
this
case. Any help or insight into this matter is highly appreciated.
Regards,
Hassaan
