Hi everybody,
I have been trying to connect USRP RIO (2954) to a Linux host computer via PCIe
and I followed the steps below, but it simply cannot recognise ("No UHD Devices
Found"). I am wondering if anyone has used USRP RIO to Linux Host (UHD) via
PCIe x4 (PCIe08371). Note that I can connect t
Hi,
Apology if this is a redundant question.
With the latest UHD version, is it possible to use B210 as a quad channel
receiver.
Dual channel, I understood, it exists, and I verified also.

Hi all
I have a single B200 with me and I want to test whether it is
receiving/transmitting the signal properly.How can i test this?
I am new to B200/SDRs and to programming too?
Thanking youRensi

Hi Rensi:
I’d suggest using the UHD utility programs that come with the B200. There is a
spectrum analyzer application, called uhd_fft, and a simple radio receiver that
can, for example, be used to test your unit with local broadcast stations in
the FM band. You’ll need a small antenna for on
You'll need an antenna that works for exactly the band that you want to
observe, but if you happen to have one, you can receive a known signal.
For example, if you're in possession of a 900 MHz band antenna, you
might look for 2G signals.
If you have an antenna that works around 100 MHz, look for
A single B210 has exactly two hardware receive channels. So, I'm afraid
that no software update ever will change that!
Best regards,
Marcus

had the perception that all 4 ports can be used as RX at a time!

Sumit, There is a T/R switch between the TX/RX and RX2 ports, so you can
only use one at a time for each channel.

No, you can't. As said: There's only two RX chains. You can switch these to
/either/ rx *OR* tx/rx.

Ahh I see there is a switch between TX/RX and RX2 ports ! Understood :)

A given RC chain can use either the RX2 port or the TX/RX port. There's just a
analog switch.

Hi again, Marcus (and all).
I have continued to try and sort out this problem and may be able to provide
some more insight, or at least failed approaches.
Another reader suggested that using STREAM_MODE_NUM_SAMPS_AND_MORE may help if
there is a setup or latency issue. So, I changed the receptio
Hi,
I want to create an artificial audio drift in transmitter side and test it
using my audio control loop in receiver. This is what I'm planning.
Take an audio wav file which is sampled at 12 kHz. Re sample it such that the
sample rate is now having a drift of 100 ppm, ie with sample frequenci
