RF Porn

Easy dedicated setup to measure H1 spectrum including RF frontend, extra optionnal sensors (magnetometer, GPS) and SDR processing. Adalm Pluto is a prior target, but could be maybe extended to other plateforms later.

(HARD) Antenna → LNA → Saw filter → PlutoSDR (SOFT) → Calibrate / FFT averaging → USB stick / Realti display

FFT 1024 averaging during 1 minute

* Pointing cold area

Acquire frequency respond of measure chain (LNA impairment, filter response) to compensate measure

* Pointing hot target area
