Problems solved by technology

[0003] 1. Commonly used measurement and measurement and control instruments are independent devices. When multiple devices are used at the same time, each independent device needs to be operated separately, and synchronous testing cannot be performed.
[0004] 2. Integrating multiple measurement and measurement and control instruments into one ATE measurement and control system can perform synchronous testing, but the synchronization accuracy is not high and cannot be controlled. The integrated ATE system is large in size, high in cost and energy consumption, and inconvenient to use

Abstract

The invention discloses a multifunctional synchronous testing device. The multifunctional synchronous testing device integrates functions of a plurality of instruments, software and hardware modular design is adopted for the multifunctional synchronous testing device and different testing functions can be achieved through different combinations. According to the multifunctional synchronous testing device, synchronous testing of the functions of the instruments is achieved, simultaneous working of the functions of the instruments is achieved under the action of the same triggering signal, corresponding tested signals are accurately acquired in time, the acquisition probability of the tested signals is increased, and real-time performance of signal processing is guaranteed. Meanwhile, the multifunctional synchronous testing device is high in synchronous precision, controllable and convenient for users to use on various synchronous test occasions.

Description

technical field [0001] The invention relates to the fields of measurement, measurement and control of electronic equipment, and in particular to a multifunctional synchronous testing device. Background technique [0002] At present, there are several test methods for measurement and control: [0003] 1. Commonly used measurement and measurement and control instruments are independent devices. When multiple devices are used at the same time, each independent instrument needs to be operated separately, and synchronous testing cannot be performed. [0004] 2. Integrating multiple measurement and measurement and control instruments into one ATE measurement and control system can perform synchronous testing, but the synchronization accuracy is not high and cannot be controlled. The integrated ATE system is large in size, high in cost and energy consumption, and inconvenient to use. Contents of the invention [0005] For addressing the above problems, the invention provides a k...
