Rohde & Schwarz AM300 2 Ch Arbitrary Waveform Generator

The Rohde & Schwarz AM300 is a 2-channel arbitrary waveform generator that combines the functionality of an arbitrary generator, function generator, and I/Q signal generator in a single instrument. It delivers custom waveforms with high signal fidelity and supports AM, FM, PM, FSK, and PSK modulation, making it suitable for research, development, production, service, and educational applications.
