1 Introduction16 Keysight N4985A Operating and Service ManualFeatures of the Keysight N4985A amplifiersThe N4985A is a high performance amplifier featuring broadband frequencycoverage.N4985A-S30 and N4985A-S50– The amplifier is designed to be a multi-use laboratory RF amplifier as a gainblock for frequency domain applications or as a time domain pulse amplifier.– The amplifier’s small size and versatile performance make it an excellentselection as a general purpose gain block with moderate power output in asingle package potentially replacing two or three narrower band amplifiers.N4985A-P15 and N4985A-P25– The amplifier is designed to be easily used in laboratory and test applications.– It is small in size and has built-in bias power supplies allowing closeplacement to the measurement or source reference plane. Its high gain helpsto compensate for system losses such as long transmission lines and systemcomponents.Model Frequency range GainN4985A-S30 100 kHz to 30 GHz 30 dBN4985A-S50 100 kHz to 50 GHz 30 dBN4985A-P15 10 MHz to 50 GHz 25 dBN4985A-P25 2 GHz to 50 GHz 27 dB
