frequency-shift keying

[′frē·kwən·sē ‚shift ′kē·iŋ]
(communications)
A form of frequency modulation used especially in telegraph, data, and facsimile transmission, in which the modulating wave shifts the output frequency between predetermined values corresponding to the frequencies of correlated sources. Abbreviated FSK. Also known as frequency-shift modulation; frequency-shift transmission.

Aktakom AWG-4151 universal generator can work not only with harmonic signals, but also has modulation opportunities and other special modes including: amplitude modulation (AM), frequency modulation (FM), phase modulation (FM), frequency-shift keying (FSK), and also operation in pulse width modulation (PWM), sweep mode, frequency and pulse bursts.
With the addition of only a few other peripheral components, the two ICs can be integrated to form a small, cost-effective transceiver capable of transmitting and receiving FM or frequency-shift keying (FSK) signals in the 860 to 965 MHz frequency range with input data rates up to 500 kbps.
The basic possibilities are amplitude-shift keying (ASKe, phase-shift keying (PSK) and frequency-shift keying (FSK).
