Universal debugging tool device for ultrashort wave transceiver unit

Abstract

The invention discloses a universal debugging tool device for an ultrashort wave transceiver unit, which comprises a radio frequency signal source, a spectrum analyzer, a matrix keyboard, a DC voltage stabilization power supply, a control processing board, a man-machine interface unit, an interface conversion board and a radio frequency cable assembly, wherein the control processing board is connected with the radio frequency signal source and carries out digital signal control for outputting two paths of radio frequency signal sources to the interface conversion board and then outputting the signal sources to a to-be-debugged radio frequency unit for being debugged; the control processing board is connected with the matrix keyboard and the man-machine interface unit; the interface conversion board is used for converting an external signal interface of the control processing board to a physical interface of a to-be-detected unit board; the control processing board provides two ways of local oscillator signals for a to-be-debugged radio frequency unit board via the radio frequency cable assembly. The matrix keyboard on the control processing board is pressed, the frequency of the local oscillator signals is changed, continuous or single-step movement is realized, working in a different state is configured via the matrix keyboard, and related functions and index performance are checked and tested.

Problems solved by technology

[0005] In the research and development stage of the product, since the development of the unit board is prior to the closing of the whole machine, each unit board needs to be tested independently before the whole machine is closed to verify the functions and indicators of the unit board, especially the receiving and transmitting radio frequency units, Since it involves joint debugging and testing of interfaces with multiple unit modules such as local oscillator, main control, baseband, power amplifier, and power supply, it takes a lot of time to build a test platform in the early stage, and a variety of RF instruments are used to replace other unit boards. In order to verify its own working performance and indicators, it is necessary to connect a variety of external cables to simulate the communication and status control between the main control and the single board. Part of the protocol verification is still difficult to achieve, and the test system becomes extremely complicated. Various temporary control lines Cables also affect the accuracy and repeatability of the test, and it takes a lot of time to build and maintain the test platform
