The Keysight / Agilent 83623A is a high-power synthesized swept-signal generator providing broadband frequency coverage from 10 MHz to 20 GHz. It combines the precise accuracy of a synthesized source with the versatility of a sweep oscillator. Designed for applications requiring elevated signal levels, it delivers +17 dBm maximum leveled power and low single-sideband phase noise, making it an excellent general-purpose source for component testing, receiver testing, and frequency conversion.
