The Keysight (Agilent/HP) 83650B is a high-performance synthesized swept-signal generator providing broadband frequency coverage from 10 MHz to 50 GHz. Combining the precision and accuracy of a synthesized source with the speed and versatility of an analog sweep oscillator, the 83650B is designed for demanding RF and microwave test and measurement applications. It delivers excellent spectral purity—including low single-sideband phase noise and exceptional harmonic performance—alongside comprehensive sweep capabilities, internal AM, FM, and pulse modulation, and up to +10 dBm of calibrated output power.
