HP / Agilent 70820A Microwave Transition Analyzer, dc to 40 GHz

The HP/Agilent 70820A Microwave Transition Analyzer is a two-channel, sampler-based instrument delivering time-domain and frequency-domain analysis from DC to 40 GHz. It characterizes fast signal transitions, modulation properties, and device gain across microwave and RF systems. The analyzer measures magnitude and phase settling times, rise and fall times, pulse parameters, group delay, and AM-to-PM conversion with picosecond-level timing accuracy.
