    摘要: A test mechanism includes test equipment to measure frequency-domain data, such as scattering or S parameters. The S parameters are transformed to a different type of network parameters, such as transmission or T parameters. Contributions of test fixtures can be easily removed for the overall T-parameter matrix of a device under test connected in cascade with the test fixture. The test mechanism provides accurate measurement of a device under test represented by a multi-port (greater than two ports) network that is cascaded with another multi-port network representing the test fixture.

    摘要: A process for preparing transparent Pigment Yellow 138 by grinding Pigment Yellow 138 in the presence of a grinding agent, preparing an aqueous slurry of the ground particles, and filtering the slurry resulting in a filter cake containing particles of transparent Pigment Yellow 138. In addition, a process for improving color strength of an ink and/or plastic composition is also disclosed by adding transparent Pigment Yellow 138 to the composition.
