MEASUREMENT DEVICE, METHOD, PROGRAM, AND RECORDING MEDIUM
First Claim
1. A measuring device comprising:
- a level adjuster that receives an output signal output from a device under test, adjusts a level of the output signal, and outputs the resulting output signal;
a characteristic measurer that receives the output signal output from said level adjuster, and measures a characteristic of the device under test; and
a level setter that sets a degree of an adjustment of the level of the output signal by said level adjuster so that a measurement error is minimum upon the measurement.

Abstract
The level of an output signal output from a device under test is easily adjusted in order to restrain an adverse effect on a result of measuring characteristics of the device under test. A measuring device includes a characteristic measuring unit for measuring characteristics of a device under test based on the output signal output from the device under test, an attenuator for receiving the output signal and adjusting the level of the output signal before supplying it to the characteristic measuring unit, and a level setting unit for setting the degree of the level adjustment of the output signal by the attenuator so as to minimize a measurement error which is caused by the characteristic measurement unit, and changes according to the level of the output signal supplied to the characteristic measuring unit.
