A high-performance, programmable signal generator for demanding out-of-channel RF receiver measurements and other stringent RF applications. It covers the frequency range from 100 kHz to 2115 MHz. This signal generator provides low SSB phase noise and spurious, high output level and level accuracy, and a full range of modulation types.a high-performance, programmable signal generator for demanding out-of-channel RF receiver measurements and other stringent RF applications.
