Re: [Discuss-gnuradio] wx_fft_sink block

Hello Abhilash, Also, please consider using QT gui instead of WX. That has nothing to do with this issue, however. WX GUI components are no longer supported and will be dropped in near future. Regards, Kyeong Su Shin On Sat, Feb 3, 2018 at 9:42 PM, Kyeong Su Shin wrote: > Hello

Re: [Discuss-gnuradio] wx_fft_sink block

Hello Abhilash, That is because the power level is relative. Unless you use a absolute power level (dBm/Hz, etc), the comparison of the power level magnitude is meaningless. The spectrum analyzer is probably giving you dB'm' readings, but the USRP is not. You cannot get absolute power level

Re: [Discuss-gnuradio] wx_fft_sink block

Hello, I am using USRP N210 with CBX daughter board. In the GNU radio I use USRP_source block followed by wx_gui_fft sink block. I input a power of -60dB to the USRP. The input power is measured using a spectrum analyzer. The RF gain in the source block is kept at 0 dB, sample rate of 25 MHz and
