UHF Narrowband Scanner and Spectrum Analyzer
System 3721
The System 3721 is a compact, rack-mountable
receiver system that is capable of receiving one, stable UHF channel (500 to 800
MHz range), sweeping across this range and performing FFT searching for energy on
programmable thresholds. When energy is found, the system will perform demodulation
and will output the demodulated signal and a DC signal proportional to the spectral
peak.
Applications
Features:
- Accepts a single analog input between 2Mhz and 3200 MHz that contains a weak UHF
signal
- Scan and tune to any 5 MHz window between 500 MHz and 800 MHz
- Executes FFT of very narrow band signal of 1 Hz resolution
- Performs an AM or FM demodulation and outputs the demodulated signal to a D/A converter
- Generates a DC signal that is proportional to the spectral peak and outputs it to
a D/A converter
