Abstract
PURPOSE: To record intermittent waveforms with high accuracy by alternately reading out memory contents and the counting time width of a counter.
CONSTITUTION: When a waveform W1 is inputted to an input terminal 1, a waveform detector 2 outputs a waveform detecting signal (a) at the instant when the waveform W1 exceeds a threshold level TH, thereby driving a write controller 4 and giving a write signal to a memory 5. In an A/D converter 3, the waveforms are converted to digital signals irrespective of the operation of the detector 2, and the waveform W1 is stored in the form of a digital signal into the memory 5. The memory 5 ends writing TM second after, and applies a start signal to a counter 8. The counter 8 begins to count the time, and at the instant when the next waveform W2 is inputted, it stops counting; at the same time, the controller 4 applies a storage command to a memory 6. Namely, only the waveform is stored in the memory and the waveform intervals are counted and held in the counter.
