The HP/Agilent 83623B is a synthesized swept-signal generator delivering calibrated output power of +17 dBm across 0.01 to 20 GHz. Built for precision signal generation in test and development environments, this instrument combines frequency accuracy with dynamic sweep capability and exceptional spectral purity. Its leveled output performance remains stable across temperature variations, while harmonic suppression and low phase noise support demanding measurement and simulation tasks across RF and microwave bands.
