Title:
誤差要因測定装置、方法、プログラム、記録媒体および該装置を備えた出力測定装置、入力測定装置
Document Type and Number:
Japanese Patent JP5177904
Kind Code:
B2
Abstract:
Measurement of error factors of a signal source when a connection tool is connected to a signal source whether error factors of the connection tool are known or not is enabled. There is provided an error factor measurement device including a connection tool characteristic measurement unit which measures characteristics of a connection tool based on measurement results of first and second signals, a reflection-to-output ratio measurement unit which measures the ratio relating to a measurement result of a reflection in a second (first) signal generation unit and a measurement result before the first (second) signal is reflected by a first (second) output terminal, an error factor recording unit which records respective components Ei1 and Eo1 of an error factor caused by frequency tracking of a first signal generation unit, and a product of respective components Ei2·Eo2 of an error factor caused by frequency tracking of a second signal generation unit, and error factor deriving unit which derive respective components of the error factor caused by the frequency tracking of the second signal generation unit based on the measurement result of the characteristics of the connection tool, the measurement result of the reflection-to-output ratio measurement unit, and the recorded contents of the error factor recording unit.
