Problems solved by technology

[0007] Desktop instrument type state controllers are basically special-purpose, developed for different types of TR components, do not support programmable parameters such as pulse width and pulse period of control signals, and have a narrow scope of application. In addition, they use CPU as the control core, which is expensive , benchtop construction is bulky and takes up valuable test cabinet interior space for automated test integration

Abstract

The invention discloses a USB-based TR component programmable state controller and a working method, including a USB interface circuit, the USB interface circuit is connected with a control circuit based on a complex programmable logic device, and the characteristic parameters of the signal are sent to the controller through the USB interface circuit. Based on the control circuit of the complex programmable logic device, the control circuit based on the complex programmable logic device analyzes the signal characteristic parameters and generates the differential nested signal required for the TR component test. USB is used as the power supply and program-controlled communication interface. USB interface devices are widely used, small and easy to use, and have higher support capabilities for the use of automatic test systems. The circuit design scheme based on complex programmable logic devices is simple, low power consumption, and low failure rate. Programmable output of state control signal for TR component testing, pulse width, pulse period, timing relationship, number of output signal channels, etc. all support programmable.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a USB-based TR component programmable state controller and a working method. Background technique [0002] TR (Transmitter and Receiver) component refers to the component that connects the antenna and the intermediate frequency processing unit in the wireless transceiver system. To realize the test of TR components, the first problem is to realize the control of the working state of TR components, which is the prerequisite for the test to be carried out. The TR component requires a total of 9 state control signals, which are the transceiver control signal, the power amplifier power control signal, the pulse modulation signal, and the sum difference control signal. Each signal includes two differential channels (taking the transceiver control as an example, the transceiver control + is positive When the pulse, transceiver control- is a negative pulse, the TR component works in th...
