SDRangel pictures and videos
Channel analyzer view
See this video for SDRangel in action on a fast laptop watching some pulses in the GSM band with the channel analyzer plugin. The new channel analyzer has even more capabilities but this demonstrates the responsiveness of the software.
See this other video of watching a FM pulsed signal in the 868 MHz ISM band. The view in the channel scope stacks the power above the phase showing the phase modulation in the signal. Here also the old channel analyzer was used.
See this video from my friend Evariste F5OEO showing the QPSK constellation of a DATV transmission. As the analyzer is generic there is no provision for de-rotating but the figure is quite visible. Alternatively you could use the scope memory feature to "take" a still image.
See this picture of the author presenting the ATV Demodulator and Modulator for amateur analog television during the last ATV meeting in Nimes, France. Thanks Michel for the picture!
