Abstract

PURPOSE: To eliminate measurement errors, etc., by generating a measurement signal and a time base marker signal to be displayed on an oscilloscope from one reference signal generator.
CONSTITUTION: The analog signal A from the signal generator 1 is level-sliced by a comparator 2 and is supplied as a square wave B to a bit comparator 5 via a counter 4. The comparator 5 turns on an analog switch 9 when a preset 8 bit pattern is attained. The switch 9 outputs the signal A output via a terminal 10 to an instrument 11 to be measured when the set 8 pit pattern is detected. The signal E delayed by the instrument 11 is displayed 13. On the other hand, the outputs of the counter 4 supplied to binary decimal coders 6, 7 are converted to decimal signals which are supplied respectively to on-off switches 14, 15. The signal F formed by the switched 14, 15 is supplied as the time base marker signal to the oscilloscope 11 via a terminal 12 and is displayed thereon in line up with the signal E. The delay time is measured by comparing this time base marker signal and the signal E.
