Frequency Calculator & Live Spectrum Analyzer

Tune carrier frequency, bandwidth, modulation, harmonics, signal power, and noise floor. The spectrum view updates using the same values used in the RF calculations, so the graph stays yoked to the math instead of wandering off into pixel folklore.

Core formulas: wavelength λ = c / f, adjusted element length = λ × velocity factor × fraction, FSPL(dB) = 32.44 + 20log10(distance km) + 20log10(frequency MHz), power W = 10^((dBm - 30) / 10). The analyzer scales the peak, noise, occupied bandwidth, sidebands, and harmonic markers from the same input values.
