The APPH is a fully contained signal source analyzer with a frequency range of 1 MHz to 7, 26 and 40 GHz. It offers an indispensable set of measurement functions for evaluating signal sources ranging from VHF to microwave frequencies but also active and passive non self oscillating devices like amplifiers, or frequency dividers. A mixed-signal system architecture with a FPGA crossspectrum engine enables very fast signal processing and ultra-low phase noise sensitivity.   For more information
