ABSTRACT:
A network analyzing apparatus that analyzes the network properties of a device under test by applying reference signals to a device under test by frequency sweeping or power sweeping comprises input device for inputting the sweep range and sweep interval of these reference signals as well as the center coordinates and radius of a test circle for testing this device under test; a measurement apparatus for measuring the network properties of this device under test and obtaining measurements for n number of measurement points determined from this sweep range and sweep interval; and a testing apparatus, with this testing apparatus finding the difference between this measurement and center coordinates and, referring to this difference and this radius, determining that this measurement that has been read passes the test if the magnitude of this referred difference is no greater than this referred radius, or is less than this referred radius.
