Re: [USRP-users] UHD release vs. gnuradio release - compatibility table?

2018-02-09 Thread Martin Braun via USRP-users
Can confirm: If you're building GNU Radio from source, it'll work with almost any version of UHD (note that on next branch, we've finally bumped the minimum UHD version, but it's something like 3.5.5 or so). -- M On 02/01/2018 05:29 PM, Ron Economos via USRP-users wrote: > I think the

[USRP-users] USRP B210 TX-Issues

2018-02-09 Thread Jonathan B via USRP-users
Hi everyone, I seem to be having issues with the B210 transmitting at an incredibly low power. I seem to be getting a 60db difference at the receiver (spectrum analyzer) between the B210 and N210 with perfectly identically configured transmissions using the simple uhd "tx_waveform" example

[USRP-users] Bandpass filters

2018-02-09 Thread Mathieu Petitjean via USRP-users
Hi everyone, As a very newbie with SDRs, I want to use an USRP to listen to two different, but close frequencies and distinguish them (the frequencies are not fixed yet). I would like to implement two bandpass filters and look at the output of both filters, but I am not sure how to proceed. Is it

[USRP-users] E310/E312 Receive on all 4 inputs

2018-02-09 Thread Ronakraj Gosalia via USRP-users
Hi folks! I am wondering if it is possible to receive on all 4 inputs at the same time on the E310/E312? I.e. is it possible to receive on TRX A, RX A, TRX B, RX B all at the same time? I tried creating a GNU Radio flowchart with this setup and got the following Runtime Error:

Hello, For more details, please find attached the received signal in the time domain. Clearly after the end of the packet, the signal takes a certain time to come back to "the ambient noise". If I zoom, I notice there is still some noise 40ms after the packet. It can disturb the reception of
