Abstract
PURPOSE: To increase the accuracy of analysis, by simplifying the circuit and increasing the accuacy of peak hold, through the use of the specific part of the waveform such as the horizontal synchronizing level of video signal waveform and specific luminance level as the gate signal.
CONSTITUTION: In measuring the level at point A of the video signal waveform 16, the gate signal 26 designating the point A apart from the head point C of the synchronizing signal on the waveform 16 by t±Δt is given to the peak holds 3, 4 of positive and negative direction, to obtain the peak hold signal 29. The signal 29 is in A/D conversion 6 and latched 7 with the timing signal 28 obtained from the signal 26. On the other hand, in measuring the time axis of the point B on the waveform 16, the threshold level 30 greater by VT than the reference value is given, the edge of leading and trailing of the signal 31 obtained with the comparison 11 of the level 30 and the waveform 16 is detected 12, the phase difference between the trigger signal 23 corresponding to the point C and the edge is sampled 13, the pulse number N is conuted 14, to obtain the time axis TX.
