FCD scanner
FCD scanner is a slow and simple implementation of a swept-tuned spectrum analyzer in Python. It can display received signal strength versus time versus frequency using a number of real-time visualizations and can also log measured data for later analysis.
It works by sweeping a radio receiver through a range of frequencies and measuring the signal power at the receiver output. Resolution bandwidth is determined by the channel filter used by the receiver and sweep time is limited by receiver settle time.
Two radio receivers are currently supported:
- Funcube Dongle Pro using the GnuRadio framework.
- VESNA wireless sensor node connected through a serial port and running the vesna-spectrum-sensor application.
