Hello

Planes transmitt pulse position modulation on 1090 MHz

I am interested in seeing these pulses like an oscilloscope

Is it possible with the SDR play ?

The pulses are 56 bits and 112 bits and are very fast

Hi
It should be possible but the software is missing AFAIK.
A possible trick would be to record I/Q as an audio file with high 3 MHz sampling rate
and then to play it back much slower in audacity or another software able to display audio waveforms.
