Sub-10 ps Pulse Generators
白皮书
Until very recently, the need for pulses with sub-10 ps rise times consisted of small niche applications at the periphery of worldwide technology research and development. However, the never ending march toward faster processing and communications technologies has pushed data rates ever higher and the corresponding signal frequencies into the 10s of GHz. To keep up, measurement systems such as the real time oscilloscope have rapidly pushed into record acquisition bandwidths of greater than 60 GHz (for example the Keysight Technologies, Inc. 90000 Q-Series 63 GHz real time oscilloscope). A whole host of important applications now demand pulse generation of sub-10 ps edge speeds. From calibration and metrology standards, to step response measurements, to characterization of devices using time domain reflectometry and transmissometry (TDR and TDT), engineering at today’s data rates and bandwidths requires ultra-fast pulses with rise times below 10 ps and frequency content well beyond 60 GHz.
