There are measured characteristics of a jig (fixture) used to calculate and measure circuit parameters of a device under test. There is provided a jig characteristic measuring device which measures the jig characteristics of a jig 3 which includes signal lines 3 a , 3 b , 3 c, and 3 d used to connect a DUT 2 and a network analyzer 1 with each other (namely, the reflection characteristics of signal lines 3 a , 3 b , 3 c, and 3 d, and the transmission S parameters), measures the reflection coefficients of the signal lines 3 a , 3 b , 3 c, and 3 d in an open state where the DUT 2 is not connected to the signal lines 3 a , 3 b , 3 c, and 3 d, measures the reflection coefficients of the signal lines 3 a , 3 b , 3 c, and 3d in a short-circuit state where all the signal lines 3 a , 3 b , 3 c, and 3 d are grounded, and derives the jig characteristics of the jig 3 based on these measured results.
