Abstract

PURPOSE: To enable a digitally sharp marker to be obtained by sequentially measuring the oscillation periods of sweep waveforms.
CONSTITUTION: This invention relates to the insertion of a marker 5 at a desired point of characteristics by branching the output of a frequency sweep oscillator 1 with a marker circuit 4 in the measurement system of inputting the sweep frequency output from the frequency sweep oscillator 1 to the circuit 2 to be measured and inputting the characteristics of the circuit 2 to be measured to a display circuit 3 thereby displaying the characteristics, wherein the oscillation periods of the sweep waveforms of the sweep frequency output are measured by inputting the sweep frequency output from the sweep oscillator 1 to a gate 11 and frequency-dividing the same and from the oscillation periods thus measured a digital oscillation frequency fx is obtained in a counter 17, then this oscillation frequency fx is compared with the desired marker frequency having been set by a marker frequency set circuit 18 in a coincidence circuit 19 and when both coincide, a marker output is produced.
