Abstract: PROBLEM TO BE SOLVED: To operate a digital oscilloscope at high speed by a method wherein a plurality of microprocessors(MPU's) for operation control are installed and their functions are divided. SOLUTION: A FIFO memory 7 which can be accessed at high speed and which can be written and read out asynchronously is installed at the front stage of a VRAM 14, and an MPU 12 for display and an MPU 21 for operation are operated in parallel.

Thanks to their parallel operation, it is not required to process an interrupt instruction during a specific period when the interrupt instruction is input from an operator panel or the like, and a response speed becomes fast.  In addition, when the dual-port RAM 30 is installed, the MPU 12 for display writes waveform data into the dual-port RAM 30 when the waveform data is transferred to the outside, and the MPU 21 for operation outputs the waveform data after that. Consequently, a data transfer rate becomes fast. Thereby, it is possible to obtain a digital oscilloscope which is easy to use and which is operated at high speed.
