2. Description of the Related Art FIG. 3 is a block diagram of a conventional general waveform measuring device. An analog measurement waveform input to the input terminal 1 is converted into a digital signal by the AD converter 1 and is taken into the RAM 3 as waveform data. Under the control of the CPU 4, the waveform data taken into the RAM 3 is stored as a waveform data file in a storage medium 5 such as an HD, FD, or ATA flash, or is input to a display control unit 6 or a condition determination unit 7. .

Is set to what processing (SP
1).

After these settings are completed, the acquisition of waveform data is started (SP2), and the acquisition is terminated after a predetermined amount of waveform data is acquired (SP3).

[0007] When the acquisition of the waveform data is completed, the acquired waveform data is judged based on the set GoNogo condition (SP4). If the judgment result is conformity, the processing after step SP2 is repeatedly executed, and if the judgment result is non-conformity, the Nogo processing preset in step SP1 is executed (SP5). After the execution of the Nogo process, the processes after step SP2 are repeatedly executed.
