precision measurement equipment power characterization application software mt993a mt993c general the maury power characterization application software is designed to operate with the ats and determine the optimum load and source termination conditions for optimizing device performance if the fixture or probe station network characteristics s2p are known the measured functions are de-embedded to the device input plane the software is provided as part of an ats system specified for power characterization see page 51 separately as model mt993a or combined with the noise characterization software as model mt993c precision measurement equipment power parameters in large signal amplifier design power output is a complex function of the input power level terminating impedances and dc bias conditions an ats operating with the maury power application software can provide fast accurate measurements of power output transducer gain power gain power added efficiency and measured input and output voltages and currents the program also permits display of 2nd and 3rd harmonic source and load impedances a unique feature of the maury software allows the user to define up to 35 output functions these functions can be used to develop specific output parameters e.g simple efficiency vswr or even control instruments e.g to control the turn-on/turn-off sequence of a high power signal source the program also has a built-in general purpose s-parameter measurement program that allows for fixed or swept bias conditions the software provides for both data and graphical hard copy outputs the block diagram below illustrates a typical measurement setup while sample output displays are shown on the adjacent page computer hardware requirements are detailed on page 51 and the measurement equipment supported is listed on page 65 a unique feature of maury ats software is the availability of the equipment driver source code which facilitates development of custom instrument drivers by the user typical setup for performing simultaneous load pull and source pull measurements maury microwave 54
