Re: (gnuradio3.8) module 'gnuradio.blocks' has no attribute 'message_sink'

Hi Criss, Unfortunately it seems there is no easy solution to this problem. But at least I can go back to Ubuntu18 which installs gnuradio 3.7 and I can still use my old codes. Regards, Ting Wu On 2021/01/15 1:49, Criss Swaim wrote: Hi Ting: I have been working on this same issue for a

[Discuss-gnuradio] Resolution of USRP N210 and N200

Hi, Both of USRP N210 and N200 have 14 bit ADC, which means a range of +/-2e13=+/-8129. However, as I tested a N210 with LFRX, I got values from -32704 ~ 30073, close to +/-2e15=32768. Last year, I also tested a N200 with LFRX, I got values from -16357 ~ 16241, close to +/-2e14=16384. The sa

Thank you for your response! We need to use the sampling rate of 4 MHz. How can I deal with this problem? Actually we have been running the same application on several USRPs (N200 and N210), and there was no such warning. Any suggestions? Ting Wu From: Marcus D. Leech [mailto:mle

[Discuss-gnuradio] About the sampling rate

Dear all, I find the sampling rate of USRP is surprisingly accurate. Now I set the sampling rate as 4 MHz, and there are always exactly 4M points between two pps signals. Even if I take off the GPS antenna, the sampling rate is still very accurate. This means I only need the GPS antenna at t

Re: [Discuss-gnuradio] Waiting too much time for the GPS to be synchronized

I think you need to put the antenna outside. In my situation, I put the antenna on the balcony. It usually takes me only several minutes to get an accurate time (diff<0.01). Wu From: discuss-gnuradio-bounces+wu.ting=comf5.comm.eng.osaka-u.ac...@gnu.org [mailto:discuss-gnuradio-bounces
