Abstract

The invention relates to the technical field of electronics, and discloses a static resistance simulation circuit. The simulation circuit includes a static resistance simulation unit for simulating static resistance of electronic equipment when an external power supply line is not powered on, a state switching unit for switching from connection with the static resistance simulation unit to connection with a main equipment simulation unit, and a state switching driving unit which is connected to the state switching unit and used for driving the state switching unit to perform switching operation when the external power supply lint is powered on. Therefore, the static resistance simulation unit and the main equipment simulation are isolated from each other in electrical connection, thereby solving the problem of excessive deviation of static resistance simulation.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a static resistance analog circuit. Background technique [0002] The static resistance of electronic equipment before power-on is an important parameter of its electrical characteristics. The test equipment can test this parameter to diagnose some failure modes of the electronic equipment. The case of burning the device when it is energized in a short circuit state. As supporting equipment becomes more and more abundant, some electronic equipment is equipped with simulators, such as missile simulators, which can replace missiles and cooperate with the completion of test training and test verification. In order to ensure that the test training process is consistent with the official product, including the inspection of static resistance, a static resistance simulation circuit needs to be designed in the simulator to simulate the static resistance of the official product. ...
