Document Type and Number:
Japanese Patent JP7478175
Kind Code:
B2
Abstract:
A signal generation unit 2, a DA converter 3, variable attenuators 40, 42, 44, and 46 that attenuate an analog signal converted by the DA converter 3, a measurement unit 6 that detects a level of the signal attenuated by the variable attenuators 40, 42, 44, and 46 and passed through one or more semiconductor components, and a control unit 7 that obtains a value of a step error, which is a correction value of an attenuation amount of the variable attenuators 40, 42, 44, and 46 in each of a plurality of steps obtained by dividing a maximum value of the attenuation amount of the variable attenuators 40, 42, 44, and 46 by a variation amount, which is a predetermined attenuation amount are included.
