Embodiment

[0027] The method that the present invention utilizes the automatic test system based on DSP high-frequency phase shift to test comprises:

[0028] The first step is to build an automatic test system for high frequency phase shift

[0029] The automatic test system for high-frequency phase shift includes: an external command input module 1, an external command interpretation module 2, an angle parameter adjustment module 3, an angle error storage module 4 and a high-frequency phase shift selection module 5.

[0030] In the second step, the external command input module 1 inputs command A, which is used to control whether to perform automatic test of high-frequency phase shift, test Y / Z direction and angle offset.

[0031] The third step, see figure 2, the external command interpretation module 2 decomposes the command A input by the external command input module 1 to form three commands: the command A1 for automatic testing of whether to perform high-frequency phase shift, t...

Abstract

The invention discloses an automatic test system and method based on DSP high-frequency phase shift. Firstly, the external command interpretation module (2) decomposes the command (A) input by the external command input module (1) to form three commands: Instruction (A1) for high-frequency phase shift automatic test, instruction (A2) and angle offset (A3) for testing Y / Z direction. When the instruction (A1) of whether to perform the automatic test of high-frequency phase shift is 1, the angle parameter adjustment module (3) first judges the instruction (A2) of the test Y / Z direction, if it is 1, then according to the angle offset (A3) Determine the high-frequency phase shift in the Y direction; if it is 0, determine the high-frequency phase shift in the Z direction according to the angle offset (A3). The angular error storage module (4) stores angular errors under different high-frequency phase shifts in the Y / Z direction. The high-frequency phase shift selection module (5) compares the magnitude of the stored angular error, and selects the high-frequency phase shift corresponding to the maximum value of the angular error as the optimal high-frequency phase shift. This method improves the testing efficiency.

Description

technical field [0001] The invention relates to the technical field of high-frequency phase shift testing, in particular to an automatic testing system and method based on DSP high-frequency phase shift. Background technique [0002] At present, the high-frequency phase shift test needs to run the program online, manually modify the offset angle, and the test efficiency is very low. Especially after the software is solidified, the manual test not only brings risks to the program stability, but also greatly reduces the test efficiency. Contents of the invention [0003] In view of the above technical problems, the purpose of the present invention is to provide an automatic test system and method based on DSP high-frequency phase shift to solve the problem of low test efficiency caused by manually modifying the angle. [0004] The automatic test system based on DSP high frequency phase shift of the present invention comprises: external command input module, external command ...
