Can SDR be used as spectrum analyzer?

We note that SDRs like the RTL-SDR could be used as a spectrum analyzer too with software like QSpectrumAnalzyer and Spektrum, however the advantage of the tinySA is that it is a standalone package with it's own screen that can easily be used in the field.

What is the frequency range of the RTL-SDR?

The RTL-SDR is a USB dongle that can be deployed as an RF-frontend as shown in Figure 3.1 a). It operates at the frequency range of 24-1766 MHz [55] , therefore, it is an ideal candidate for the LPWAN technologies that operate in the sub-1 GHz frequency band.

What is RTL-SDR sample rate?

The maximum sample rate is 3.2 MS/s (mega samples per second). However, the RTL-SDR is unstable at this rate and may drop samples. The maximum sample rate that does not drop samples is 2.56 MS/s, however some people have had luck with 2.8MS/s and 3.2 MS/s working well on some USB 3.0 ports.
