In this paper the author introduces a design approach of noise receiver chain of noise figure measurement function in domestic 3674 vector network analyzer. Noise power reception of noise figure measurement function in the vector network analyzer requires a receiver chain with low noise figure; accurate reception of noise power is the key to ensure low noise figure indicator and large dynamic range of noise receiver. In this paper, the design scheme and technical indicators of noise power receiving chain are discussed. this paper mainly discusses areas such as the noise receiver analog chain, distribution of ADC index, the design scheme of intermediate frequency filtering and the test effect of low noise amplifier using noise figure measurement function.

3D printing has the potential to be widely applied in mass production with customization. However, iterating the computer-aideddesign (CAD) models and printing configurations to obtain the desired object mostly remains a tedious trial and error process. Various automation techniques have been proposed to facilitate the CAD model creation process and a few of them are designed specifically for 3D printing. We propose an automation framework for industrial 3D printing, which translates both constraints and requirements into technical parameters for corresponding geometric optimization for CAD models and G-code generation for the printing tasks. this framework aims to further close the gap between rapid prototyping and mass production for industrial 3D printing.
