[USRP-users] TwinRx frequency range

2018-03-23 Thread Matis Alun via USRP-users
Hi, The TwinRx frequency specifications is from 10MHz to 6GHz. However, some tests shows that I can select the center frequency around 10 MHz with a sampling frequency of 25MHz which allows to make some acquisitions in the HF band (3-30 MHz) with a very good quality. My question is: why the sp

yes, its seems that we loose several dBs but which can be widely compensated by the extremely large TwinRx gain range. Le 24/03/2018 à 06:38, Marcus D. Leech via USRP-users a écrit : > On 03/24/2018 12:41 AM, Matis Alun via USRP-users wrote: >> Hi, >> >> The TwinRx freque

[USRP-users] multiple rx streams

Hi usrp users, Using an older release of UHD, I was able to build 2 rx streams (in order to process data of each stream in a separate process) using this kind of code: usrp->set_rx_subdev_spec((std::string)"A:0 A:1"); uhd::stream_args_t stream_args("sc16",wire_format); stream_args.channels.push

Hi everybody, I saw that a /tmp/uhd.log is created when running a sampling program and it is becoming very large if the program runs during a long time. How can we disable the logging messages ? I tried to set the environment variable UHD_LOG_LEVEL or the pre-processor -DUHD_LOG_LEVEL directive

Hi, I remark that the "time_spec" passed to the "recv" method of an rx_streamer is not in exact relation with the length of the received vectors. For example, when receiving buffers of length 16384 at Fs=362319 Hz, the buffer length should be equal to (16384+1)/362319=0.0452225 seconds, while t
