Abstract

The invention discloses a circuit board automatic commissioning method and system based on LabVIEW and a spectrum analyzer platform, wherein the board to be tested is plugged into the platform, and the spectrum analyzer platform and the signal source analyzer are connected through a LAN port. Connecting, the method comprises the following steps: prompting to connect each port test cable; calling the library function of the DLL related to SPI communication in the spectrum analyzer industrial computer to initialize the SPI bus, and the SPI bus is used for the spectrum analyzer industrial computer and the reference board The communication between the controllers; based on related library functions, the control set register controls the opening of different signal output ports on the reference board, controls the microwave switch to switch paths, and makes each output port signal input to the signal source analyzer; signal source analysis The meter reads the signal amplitude to determine whether there is a fault. The invention realizes the automatic commissioning of the spectrum analyzer circuit board, saves manpower and improves the commissioning efficiency.

Description

technical field [0001] The invention belongs to the field of circuit board debugging, and in particular relates to an automatic circuit board debugging method and system based on LabVIEW and a spectrum analyzer platform. Background technique [0002] With the continuous development of the domestic microwave radio frequency measuring instrument market, the market demand for excellent measuring instruments such as AV4051 series spectrum analyzers continues to increase, and the production and debugging of the whole machine have been improved. The commissioning process method from the board level to the whole machine is proposed higher requirements. In the board-level debugging process of similar products in the past, during the process of testing different indicators, the debugging personnel set the relevant functions of the instrument under test and the measuring instrument as needed, and manually recorded and sorted out various indicators. The efficiency is low, and the poss...
