Functions - Signal Generator

GAO1502 is CPU-controlled high accurate RF signal
generator with frequency ranging from from 300kHz to
300MHz. Besides the excellent AM and FM modulation
function, its output levels vary in 0.1dB step. It is
widely used in research & development and production
testing of AM/FM receiver, civil-band transceiver,
radio remote –control toys, wireless telephone as well
as in radio teaching laboratory.
