Abstract
A waveform data acquisition module acquires the waveforms of electrical signals for multiple channels. A memory controller continuously writes a digital signal Sto one from among a first memory unit and a second memory unit. When a given memory unit has become full, the memory controller notifies an external higher-level controller that the corresponding memory unit is full and switches the wiring target to the other memory unit.
