Open offset canceling method and an impedance measuring apparatus using the method |
摘要 |
A method for finding the impedance of a device under test using an impedance measuring apparatus having a modem-type auto-balancing bridge, two or more measurement signals, each of which has a different phase with respect to the reference signals supplied to the modem inside said auto-balancing bridge, are applied to a device under test; the impedance of this device under test is measured when each of the measurement signals is applied to the device under test; and the impedance of this device under test is found using the above-mentioned phase and the impedance measurement value of each of these measurements.
