ABSTRACT:
There is provided an error factor measurement device for measuring an error factor in a switch branch signal source including a signal source and a switch, and the error factor measurement device includes a reference error factor component recording unit which records respective components E12a, E21aof a frequency tracking error factor when a predetermined output terminal is connected to a signal source, a derived error factor product recording unit which records an error factor product E12b×E21bwhich is a product of respective components of a frequency tracking error factor when respective multiple output terminals other than predetermined output terminal are connected to the signal source, an error factor ratio deriving unit which derives an error factor ratio E21a/E12a, and a frequency tracking error factor deriving unit which derives E12b, E21bbased on the error factor product and the error factor ratio, where E21a/E12a=E21b/E12bholds.
