Measurement test system for two-port component between any two points

Abstract

The invention discloses a measurement test system for a two-port component between any two points, which comprises a power supply part, a control part, an action part, a measurement test part and an external interface, wherein the power supply part comprises an AC / DC power supply module and a multi-path DC / DC isolation power supply module; the control part comprises an operation display module, acontrol storage module and an isolation and driving module; the external interface is a connector in a related form; the action part comprises a measurement test point switching module and an analog signal switching module; and the measurement test part comprises an AD acquisition processing module and a voltage and reference module. According to the invention, through the design of the measurement test point switching module and the analog signal switching module, the scale of the measurement test point switching module can be randomly expanded according to the requirements of a user, and theautomatic measurement test function of a two-port component between any two points is realized; due to the design of the measurement test point switching module, the function of switching among the most measurement test points at will is achieved through the least switches, and due to the design of the analog signal switching module, switching between the positive excitation signal and the negative excitation signal between any two measurement test points is achieved.

Description

technical field [0001] The invention relates to a two-port component measurement and testing system between any two points, belonging to the technical field of electronic and electrical measurement and testing. Background technique [0002] At present, two-port component measurement and test systems on the market are relatively common, but most of them only have two external measurement and test interfaces. Different points to be measured are connected to the measurement and test system for measurement and testing, and the relevant data is recorded manually, which significantly increases the workload of the operator, making the measurement and testing efficiency low, and due to manual intervention , it is difficult to guarantee the consistency of measurement test data. [0003] At the same time, there are also some two-port component measurement and test systems on the market. Although they have the function of automatic recording of measurement and test data, the limited e...

[0002] At present, two-port component measurement and test systems on the market are relatively common, but most of them only have two external measurement and test interfaces. Different points to be measured are connected to the measurement and test system for measurement and testing, and the relevant data is recorded manually, which significantly increases the workload of the operator, making the measurement and testing efficiency low, and due to manual intervention , it is difficult to guarantee the consistency of measurement test data

[0003] At the same time, there are also some two-port component measurement and test systems on the market. Although they have the function of automatic recording of measurement and test data, the limited external measurement and test interfaces still cannot get rid of the high dependence on on-site labor.

[0004] In addition, there are still a small number of two-port component measurement and test systems on the market that have more external measurement and test interfaces, but they do not have the conditions for arbitrary and convenient expansion, and the operation process is complicated, requiring high operator experience and skills. , general personnel cannot use this type of measurement and testing system to work efficiently and reliably, and this type of measurement and testing system still cannot meet the needs of efficient automated measurement and testing of electronic and electrical systems with an increasing scale
