摘要： A transmission line impedance compensation method includes the step of providing a measurement device that is adapted to source a test signal having a frequency to a device under test and to determine a corresponding impedance of the device under test using an auto-balanced bridge technique. A first transmission line, a second transmission line, a third transmission line, and a fourth transmission line are connected to said measurement device. An end of the first transmission line is connected to an end of second transmission line. An end of third transmission line is connected to an end of fourth transmission line. A combined phase delay of the connected first and second transmission lines, and a combined phase delay of the connected third and fourth transmission lines, are measured by the measuring device. The device under test is connected to the first transmission line, the second transmission line, the third transmission line, and the fourth transmission line after measuring the phase delays. The corresponding impedance of the device under test is determined based on both of the phase delays.

摘要： An AC impedance measurement system is used for measuring the impedance of a DUT. A measured voltage is applied to a first DUT terminal by a first digital to analog converter, the voltage appearing at the second terminal of the DUT is monitored through an analog to digital converter and forced by a second digital to analog converter to a desired negligible value, and a digital controller determines the impedance of the DUT from the measured voltage and the current necessary to force the voltage appearing at the second terminal to the desired negligible value.
