The Agilent 83623A synthesized sweeper is the standard of excellence for applications requiring the high performance and accuracy of a synthesized source and the speed and versatility of a sweep oscillator. Synthesized broadband frequency coverage and precise 1 Hz frequency resolution (Opt 008) are generated by indirect synthesis, enabling the Agilent 83623A to achieve low single-sideband phase noise performance. It delivers the harmonic performance of 25 dB below the carrier from 2.0 to 20 GHz.
