A calibration procedure for correcting two port frequency measurements. Calibration standards are initially connected to port one of a network analyzer and individually measured. This process is repeated with port two of the analyzer. A jumper which is used to bridge ports one and two is then connected to port one. At the far end of the jumper, three references are sequentially connected and the combination of the jumper and the terminations are measured. The raw data measured thus far is then processed to extract the two port electrical parameters of the jumper. The measured jumper is then bridged between ports one and two, and a series of measurements are made. Using the known electrical characteristics of the jumper, an intervening network is completely characterized and the measured S and actual S parameters of any device to be tested are relayed.
Method For Correcting Reciprocity Error In Two Port Network Measurements
A method for correcting reciprocity error in two port network measurements, in which an iterative algorithm is used to obtain an optimal symmetric matrix approximation to a measured 2Ã2 reciprocal network. The algorithm smooths measured data to obtain a low noise floor on measurements related to mode conversion in cables and connecting hardware. A geometric interpretation is used to approximate a measured data vector with the closest vector which satisfies the reciprocity constraint. An initial point in the constraint surface (reciprocity manifold) is located, and another point which is a better approximation of the measured data vector which satisfies the reciprocity constraint is generated. By repeating this process, the closest point in the manifold is quickly located. This closest point defines a reciprocal matrix which can be used to estimate the actual device under test (DUT) parameters.
A closure device includes a female member which is open at the front end thereof and a male member which is receivable through the open front end of the female member for releasably securing it in a locked position in the female member. The female member includes a top wall having a substantially rectangular aperture therein, and the male member includes a resiliently depressible button portion which is of substantially rectangular configuration and is receivable in the aperture in the female member for securing the male member in the locked position. The female member further includes a pair of spaced alignment tabs which extend inwardly into the open front end thereof for guiding the button portion of the male member into the aperture when the male member is inserted into the female member. The closure device is operable in combination with a pair of plate-like buckle members for securing the buckle members together to form a buckle.

Abstract:
The invention provides a slip layer substrate which can reduce the thermal residual stresses between components induced by their mismatch of thermal expansion, thus greatly improve the reliability of electronic packages. The slip layer substrate comprises: a base material; a first metallization layer formed on the base material; a first diffusion barrier layer formed on the first metallization layer; a slip layer formed on the first diffusion barrier layer; a second diffusion barrier layer formed on the slip layer; and a second metallization layer formed on the second diffusion barrier layer.
