測定器
Document Type and Number:
Japanese Patent JP7379642
Kind Code:
B2
Abstract:
To improve the display synchronism of an input signal with a computation result in a measuring instrument having a real-time computation function.SOLUTION: A waveform memory unit 120 in which data of an input signal is stored includes a waveform memory 122 and a first memory control unit 121 for outputting address information for storing the data of an input signal in the waveform memory, and a computation unit 130 includes a signal computation unit 132 for performing a prescribed computation for each measurement section, a second memory control unit 133 for associating computation data with the address information, and a computation result memory 134 for storing the address information and the computation data. A display control unit 141 associates the computation data with the data of the input signal stored in the waveform memory 122 on the basis of the address information stored in the computation result memory 134 and thereby causes the computation data to be displayed at the position that corresponds to a measurement section in which the computation is performed.SELECTED DRAWING: Figure 1
