Spectral purity is the key contribution of the Agilent 8662A signal generator, making it ideal for many radar, satellite communication, and phase noise measurement applications. Typical absolute phase noise performance of this generator at a 1 kHz offset is as low as -135 dBc/Hz, depending on the band of operation. The frequency range of the Agilent 8662A is 10 kHz to 1280 MHz. It offers versatile AM/FM, using either internal 400 Hz and 1 kHz rates or externally applied modulating signals.
