Hi I have 2Questions I was install Linus Ubuntu 16.04 LTS, sudo apt-get update sudo apt-get upgrade and install uhd and gnuradio (https://kb.ettus.com/Building_and_Installing_the_USRP_Open-Source_Toolchain_(UHD_and_GNU_Radio)_on_Linux) and uhd_images_downloader uhd_image_loader --args="type=usrp2,addr=192.168.10.2" benchmark_rate --tx 10e6 --rx 10e6 and test it tx_waveforms --rate 10e6 --freq 100e6 then Using Device: Single USRP: Device: USRP2 / N-Series Device Mboard 0: N210r4 RX Channel: 0 RX DSP: 0 RX Dboard: A RX Subdev: BasicRX (AB) TX Channel: 0 TX DSP: 0 TX Dboard: A TX Subdev: BasicTX (AB) Setting TX Rate: 10.000000 Msps... Actual TX Rate: 10.000000 Msps...
Setting TX Freq: 100.000000 MHz... Actual TX Freq: 0.000000 MHz... 1. Why Actual TX Freq is 0?? And when I run uhd_fft , I can see only 0hz signal. But I set center freq 100Mhz. 2.I try to example (uhd_tx_dpsk of gr-uhd) and run in gnuradio-companion and see flowgraph, but I measured signal using spectrum analyzer I can't see signal. I put subdev A:AB in USRP SINK block and antenna is TX/RX. What should i do for transmit dpsk signal? Windows 10용 메일에서 보냄
