The Keysight (Agilent) 83631B is a synthesized signal source engineered for precision RF testing and system integration. Operating from 45 MHz to 26.5 GHz with 1 Hz frequency resolution, it delivers stable, repeatable signal generation across microwave and millimeter-wave bands. The instrument features rear-panel output connectivity and operates without front-panel controls, positioning it as a dedicated component within automated test systems. Output power ranges from −20 dBm to +10 dBm, with maximum leveled output of +13 dBm below 20 GHz and +10 dBm at frequencies up to 26.5 GHz.
