Abstract:
1. An elastic wave measurement apparatus configured to measure response characteristics from a plurality of elastic wave devices, the apparatus comprising: a high-frequency signal generator that generates a high-frequency signal that is input to an elastic wave device among the plurality of elastic wave devices based on an input destination; a switch that sequentially switches the input destination of the high-frequency signal among the plurality of elastic wave devices, from the elastic wave device to which the high-frequency signal is being input to another elastic wave device among the plurality of elastic wave devices, before a detection time at which an output signal from the elastic wave device is detected; a plurality of detectors each associated with a corresponding elastic wave device among the plurality of elastic wave devices, that each detect an output signal of the corresponding elastic wave device at a time that is an analog to digital converter that sequentially receives the detected output signals from the plurality of detectors at the different times; and a measurement device that measures elastic waves excited at each of the elastic wave devices, based on an output from the analog to digital converter.
