Abstract: The current measuring device includes an upper solution chamber (3) and a lower solution chamber (8) whose bottom has a support layer (5) and measures a current flowing via an artificial lipid bilayer membrane (2) formed on a small hole (4) of the upper solution chamber (3), wherein the lower solution chamber (8) is provided below the upper solution chamber (3) by being surrounded with a bottom plate (6) and an interval keeping member (7a).

Abstract: Two ends of a transmission line whose electrical characteristics per unit length are known are connected to associated measurement ports of a network analyzer. A short standard is shunt-connected to at least three points in the longitudinal direction of the transmission line, and electrical characteristics are measured in a short-circuited state, thereby calculating error factors of a measurement system. Then an electronic device to be measured is shunt-connected to the transmission line, and electrical characteristics of the electronic device are measured. Then the error factors of the measurement system are removed from the measured values of the electronic device to be measured, thereby obtaining true values of the electrical characteristics of the electronic device to be measured. Accordingly, a highly accurate high-frequency electrical characteristic measuring method that is not affected by connection variations can be implemented.

Abstract: A cable tester that tests cable and that determines a cable status includes a pretest module that senses activity on pairs of the cable and that selectively enables testing based on the sensed activity. A test module is enabled by the pretest module, transmits a test pulse on one of the pairs, measures a reflection amplitude and calculates a cable length. The cable status includes an open status, a short status, and a normal status. The test module determines the cable status based on the measured amplitude and the calculated cable length. The test module measures received signals on at least one other pair after transmitting the test pulse on the one of the pairs, compares the received signals on the at least one other pair to a predetermined threshold, and determines a pair short status between the one of the pairs and the at least one other pair if the received signals exceed the predetermined threshold.

Abstract: A method and apparatus for statistical compilation is presented. A statistic component portion for each statistic is stored in each a plurality of banks in a multi-location memory. At least one statistical update stream is received. Each statistical update stream includes a plurality of statistical updates, where each statistical update includes a statistic identifier and an update operand. Received statistical updates are scheduled to produce a scheduled update stream. A control block executes the updates. The control block retrieves the current value of one of the statistic component portions from memory and combines the current value with the update operand of a corresponding statistical update. The resulting updated component value is then stored back into memory. When a processing block issues a statistic request, the control block fetches each of the component portions from memory and combines the component portions to produce a total statistic value.

Abstract: A capacitance probe for thin dielectric film characterization provides a highly sensitive capacitance measurement method and reduces the contact area needed to obtain such a measurement. Preferably, the capacitance probe is connected to a measurement system by a transmission line and comprises a center conductive tip and RLC components between the center conductor and the ground of the transmission line. When the probe tip is in contact with a sample, an MIS or MIM structure is formed, with the RLC components and the capacitance of the MIS or MIM structure forming a resonant circuit. By sending a driving signal to the probe and measuring the reflected signal from the probe through the transmission line, the resonant characteristic of the resonant circuit can be obtained. The capacitance of the MIS or MIM structure is obtainable from the resonant characteristics and the dielectric film thickness or other dielectric properties are also extractable.
