Abstract
The dynamic range improvement and realization of the acousto-optic spectrum analyzer are reported. When two RF signals of equal strengths and frequencies f1 and f2 are applied simultaneously to the signal Bragg cell, the analyzer demonstrates a dynamic range of 50 dB and frequency resolution 10 kHz.
