发明名称 Method and arrangement for measuring the attenuation-versus-frequency characteristics of two-ports
摘要 A method and device for quickly performing simple frequency-response measurements on two-ports. A controllable-frequency constant-output-voltage A.C. voltage generator has its output connected to the input of the two-port of interest. A sawtooth generator applies a control sawtooth to the frequency-control input of the A.C. voltage generator, to effect a continuous frequency variation. A peak-value-storing digital meter connected to the output of the two-port during the frequency runthrough registers the peak output signal developed by the two-port, and also generates a control signal dependent upon detection of a peak value. The sawtooth signal is furthermore applied to a circuit which correlates the value of the sawtooth with successive ones of at least four successive frequency ranges. Simple indicators, such as a set of small lamps, are used to indicate which frequency range contains the registered peak value, for example with only the first indicator lamp lighting up when the first frequency range is the one, with the first two lamps or just the second lamp lighting up when the second frequency range contains the registered peak value; and so forth.
