ppm offset或frequency offset:频率偏移,俗称偏频,一般由于硬件信号的源宿时钟不同步造成。 先看看kalibrate的基本用法: #!bash :~# kal -h kalibrate v0.4.1-rtl, Copyright (c) 2010, Joshua Lackey modified for use with rtl-sdr devices, Copyright (c) 2012, Steve Markgraf Usage: GSM Base Station ...
RTL2832SDR电视棒就是一个ADC,采样得到的I/Q数据会传送到连接的电脑上。 我们通过下面的代码进行数据采集: rtl_sdr -s 2400000 -f 88500000 -g 48.0 capture.bin 意思是采样率(sampling rate)设置为2.4MHz,调频率(frequency)到88.5MHz,增益(gain)设置为48dB,数据保存文件为capture.bin。 回车之后命令行输出显示...

1 PPM TCXO, SmA F connector and aluminum case with passive cooling. Music from 25 MHz to 1760 MHz bandwidth. Perfect for using as a radio scanner with free computer based software such as SDR, HDSDR, SDR-Radio, Linrad, GQRX or SDR Tap on Android. Great for many applications including...
I'm going to save the signal processing details for the next write-up as I feel it deserves a more in-depth explanation. But for now, the main objective is just to verify my RTL-SDR dongle works and I've selected the right antenna. So I simply took each radio station's frequency, ...
如果需要调整接收模式的话,使用在frequency标签下面左侧的菜单。在这里你也可以调整信号带宽,典型的NFM(窄带FM)信号应该在12kHz宽左右,而典型的FM广播信号应该在192kHz宽左右。 如果需要调整频率的话,使用右边的VFO tuning窗口,如果你没看到的话,也许需要点击VFO tuning标签来让它显示,或者也许是你的窗口过小...

What is the RTL-SDR frequency range? This is dependent on the particular tuner variant used in the dongle, and the particular implementation. Some dongles, like our RTL-SDR Blog V3 and V4 also have hardware enhancements that enable reception below 24 MHz. ...
