  • Publication number: 20210325283
    Abstract: A master unit includes a synchronization signal source that generates a synchronization signal and a synchronization signal distribution adjustment circuit that adjusts a distribution timing of the synchronization signal to each of slave units. The synchronization signal distribution adjustment circuit includes a period measurement circuit that measures a period of the synchronization signal output from the synchronization signal source, a time difference measurement circuit that measures a time difference between a time point of the synchronization signal issued from the master unit to the slave units and a time point of the synchronization signal returned from the slave units to the master unit, and a delay circuit that delays the issuing time point of the synchronization signal to be transmitted from the master unit to the slave units based on the period of the synchronization signal and the time difference.

  • Publication number: 20200264081
    Abstract: In an FPGA, waveform data to be sent from the FPGA to a DAC is stored, and a logical circuit is configured from a detection circuit for extracting test force value and elongation value signal components from a signal input from an ADC, an offset subtractor, and a gain multiplier. The detection circuit extracts a resistance component proportional to the test force and displacement. In the detection circuit, an expression that includes a harmonic component of an odd multiple of the carrier frequency is used as a correlation function for extracting the resistance component. As a result, it is possible to obtain calculation results at a sampling frequency that is higher than the carrier frequency.
