Digital test device

Abstract

The invention provides a digital test device. According to the technical scheme, a correcting device is provided with an E4440A spectrum analyzer, an E4438C digital vector signal generator, an MG3691A signal generator, an E4416A power meter, a 5343A counter, a TR2001 rubidium clock, an 8902 measuring receiver and DS-1A distortion standards, and TD-SCDMA digital modulation related software matched with a 5S1G4, a 10W 1000C power amplifier, a 3499B programmed switch, the E4440A and the E4438C is additionally provided to achieve correcting work. The digital test device aims to search for a license plate location and character segmentation algorithm with good self adaption in various scenes, and solve the problem that previous morphological structure elements are difficult to select in a self-adaption mode and the problem of the self-adaption segmentation of characters of different sizes.

Description

technical field [0001] The invention relates to a digital test instrument, in particular to a digital test device. Background technique [0002] As a 3G standard with independent intellectual property rights in China, TD-SCDMA was officially adopted by ITU in 2000 and became one of the international mainstream standards for the third generation of mobile communications. At the same time, my country is also further expanding the application of TD-SCDMA in the military field, which has broad prospects for development. [0003] Among the related test equipment of TD-SCDMA, the comprehensive tester for TD-SCDMA mobile phone and base station is widely used. To ensure the normal operation of the corresponding equipment, it is indispensable to carry out scientific calibration. [0004] The patent of the present invention establishes a TD-SCDMA digital mobile communication comprehensive tester calibration device through the calibration principle of key parameters, and completes th...
