The second volume describes ultra-high-speed and ultra-wideband spectrum analyzers (including digital, real-time and with microwave in tens to hundreds of gigahertz), signals (including logic), chains and serial buses .. The integration of devices with computer mathematics systems is described . For the first time, monolithic chips of the subnano- and picosecond time range with operating frequencies up to 100 GHz and a technique for monitoring and testing ultra-high-speed radio, electronic and electrophysical devices are described. Described work with spectrum analyzers with tracking generator. Special-purpose devices are considered: modulators of laser diodes and light-emitting grids , Electro-optical cell control modules, Multidomain Oscilloscopes of Mixed Signals , pulse and optical reflectometers , Optical spectrum analyzers , Ground radar , Heavy Duty Pulse Electronics and Energy Devices. For a wide range of readers.
