Abstract
PURPOSE: To measure the details of characteristics accurately by a method wherein the curves of frequency characteristics brought about by wide band and partial sweepings are simultaneously displayed, while the whole characteristics of the circuit to be measured are grasped.
CONSTITUTION: An input unit 11 allows a memory unit 12 to memorize such items of information beforehand as the starting and terminating frequencies of sweeping in terms of wide band sweeping; the central frequency of partial sweeping as well as the width of sweeping and furthermore the number of sweeping steps common to both the sweepings. In the case of the wide band sweeping, a operation unit 15 obtains information about the starting and terminating frequencies of sweeping as to the wide band sweeping and the number of sweeping steps, and the device computes the quantity of frequency steps, then outputs a digital signal to a frequency synthesizer 16. As the wide band sweeping is terminated, the partial sweeping is started.
