Abstract

PURPOSE: To solve the point of problems that respective marker methods have by combining the respective advantages of a digital marker method and a frequency marker method.
CONSTITUTION: In the spectrum analyzer wherein the marker signal of a high frequency is changed over by receiving signal with time and is inputted as an input signal and this input signal upon receiving and detecting is separated to a marker signal and a receiving signal and these are respectively displayed on the sam indicator; the marker signal having high frequency stability and corresponding to a reference frequenc is generated in a reference marker signal generating part 41 constituted by plural oscillators of high frequency stablity and the output thereof is delayed for a specified time in a marker delay part 48. The reference frequency is interpolated by the delay signal thereof and the marker signal indicating the accurate frequency of the receiving signal is displayed
