Method and device for generating transceiver switching control signal supporting multi-t/r component testing

Abstract

The invention discloses a method and a device for generating a transceiving switching control signal supporting multi-T / R component testing, including a T / R component state controller, and the T / R component state controller is respectively connected with a plurality of digital T / R components to be tested. The components are connected, the T / R component state controller is connected to the digital oscilloscope through the transceiver switching line, and a plurality of digital T / R components to be tested are respectively connected to the digital oscilloscope through the switch network; the T / R component state controller includes a transceiver switch unit, and the transceiver switching unit is used to send a synchronous signal to the digital oscilloscope when the state of the digital T / R component to be tested changes. The invention only needs one output port of the control signal for transmitting and receiving switching, and can satisfy the test of the switching time of transmitting and receiving of multiple components. The output of the transceiver switching control signal of the present invention can be strictly synchronized with the transition of the transceiver state of each component.

Description

technical field [0001] The invention relates to a method and a device for generating a transceiver switching control signal supporting multi-T / R component testing. Background technique [0002] T / R components are the most numerous and most important type of microwave multifunctional components in phased array electronic equipment. It is based on a time-sharing working system. In the transmitting state, the power of the transmitting excitation signal is amplified, distributed through the network and fed back to the antenna element, and phase weighted to form a good transmission pattern; in the receiving state, the signal from the antenna element is Weak small signals are amplified without distortion and low noise, and amplitude and phase weighting are also performed to form a good receiving pattern. The transceiver switching time is an important index to evaluate the performance of T / R components, which characterizes the time required for the transition from transmission to ...
