Hi All,
I'm using 2 USRP1s to send and receive a simple sine wave using UHD. The
TX/RX frequencies are 2.45 GHz as I have RFX 2400 as daughterboards.
I use the UHD example tx_waveforms to transmit a sine wave of 10 kHz, sample
rate 250ksps. I received the waveform at the other end using the UHD e
Hello GNUradio users,
I'm only a beginner with this software, only done an audio test with
GRC, but saw discussions in the mail archive about improving the fft
sink. haven't tried the qtgui yet (but qwt is known to me), and I
thought this project may drag some interests here:

Among some of the additions in there was the new library libvolk_orc -
which apparently requires orc to build. Can you give a brief bit about
the use of orc? I gather from google that it is the oil runtime
compiler, and that it is part of the liboil, which seems to have at
least a related set of go
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

But I have to ask, how did you blow this capacitor, and what else is
damaged as a result?
Marcus,
I cannot answer neither of your questions:
at some point i realized that the capacitor was blown.
I have no way of knowing if anything else is damaged
(at least visually everything seems OK).

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

Hi all,

Can someone help with the exact specs.

Hi,
I was able to install the UHD on my host and as well the firmware on the SSD,
I changed the USRP2 ip address to 192.168.0.2.
The uhd_find_devices correctly finds the device:
$ uhd_find_devices
linux; GNU C++ version 4.4.3; Boost_104000; UHD_002.20110131232513.d46058d
